Optika’s B 350

The time we considered Chinese microscopes as vulgar copies of mainly Japanese hits (folded tin with play microscope optics) is over. China now produces good instruments and as a sample of that I have the honour of presenting the Optika B 350, with which I was allowed to play a few weeks.
‘A real Leica,’ exclaimed a friend of mine on seeing it on my desk. Well, the stand is very Leica like. Not very original, but a good modern and sturdy stand. Optika somewhere on its website boasts that their
better microscopes originate from the same factory where Leica orders. Do not know. But anyhow this is a good sturdy stand, ergonomically spoken very much okay, heavy, thanks to the inbuilt transformer for the led illuminator (12V) and your image does not come in trouble by a bonk on the table.

Led I said already with an enormous output, sometimes too much for low power. ‘We know,’ Optika said, ‘and are working on it’. I used an ordinary neutral density filter. This is some kind of critical illumination, no Koehler. But it works fine as it does on a lot of modern microscopes of different brands. The collector lies high and although there is a hint to shade it from the outside world I had to use tape and cardboard to have it not shining into my face.

With this kind of light one has to centre the (Abbe) condenser and the manual agrees. But the manual does not tell how. There is no projection image of the filament on the condenser diaphragm. Visually centering no way. So I had to use a centering telescope and having done, images had improved considerably. Mechanical a weakness in my opinion is that the two centring screws have to keep as well the condenser in its place.


The ergonomic features are great. You find coarse and fine focusing on axis on the left side. On the right side only fine focusing by means of a big wheel with finger holes. Even if your right hand is blind you’ll find this knob ánd the knobs for moving the slide holder ánd the knob for regulating the light output. That means one can observe the secrets of life by constantly having the eyes above the eyepieces. All knobs are covered with just soft enough rubber or something what feels like rubber.


Four achromatic objectives on the four fold fixed nose piece: 4x, 10x, 40x and oil 100x. NA the usual. If you want a handy 20x or a sometimes useful dry or immersion 63x, go to the concurrence for the latter or to Optika for the 20x. Compared to some Olympus, Zeiss and Leica of the same values and the same recent make they matched. The Optika come sure from a Chinese factory, the great names probably from the same mother. So the Chines win the competition in price and they have the same serious build. All with standardized Royal Microscopic Society thread, so go hunting on eBay if you want more and different. Good is that objectives not in use look through the back window, plenty of place on the table for manipulation.

Eyepieces gives a field of 18 and have a diam of 30 mm, so big fields and with the supplied objectives a lot of unsharpness on the periferie. This is no drawback if you use a small Chinese microscope camera for its small sensor will not see the periferie but for those who go full size we recommend the Plan objectives. Fase is also an option but I did not test that.

Standard a binocular tube with only one pipe with collar correction. This means for people with eyes with different dioptervalue they can correct for that. But only one means you have no means to parfocalize objectives. And I must admit: they are not parfocal. On the instrument I overviewed not in a way I lost my subject, but…  Surprisingly the phototube of the trinocular can be screwed in and out an that means that after a lot of trial and error one can achieve sharp pictures on seeing them sharp. Thanks.

The cons and pro of this instrument, very nice, ergonomical and mechanical excellent stand, good optics, great illuminator, big table, nice phototube (extra),

Not satisfying: centring condenser difficult, illuminator shines directly in eyes.


Prices (Dutch dealer Abro) :

Basic with four objectives € 470

id. with photo trinocular tube € 655,00

with plan achromatic objectives € 745,00

ZEISS OPTON W – Let’s make things better

Posted by janvangelderen on March 19, 2007


Working a lifetime (I’m 67 now) with microscopes of different brands and types I have learned the strong and weak points of many microscopes. Every microscope has weak points, even those instruments you can trade for a new sports-car. Generally spoken the worst instruments are those which are designed by the marketing department of the firm, being Wetzlar, Jena or Tokyo based. Now I have come to an instrument which comes near to perfect, was to expensive for the market and for that reason was brought in its early youth to the churchyard.

I have fallen in love with the Zeiss Opton Stativ W.


The W is one of the first postwar instruments, and designed from scrap by refugees.  In 1945 about sixty Zeiss people fled from Jena to Oberkochen in the free world because they did not want to be send to Russia or elsewhere in the communistic world to develop ‘communistic’ instruments. They were not that welcome in the Zeiss family and after difficult negotiations they started there own  factory, the Opton Optische Werke Oberkochen. Zeiss owned 95% of the company of brave technicians. While Kurt Mitchel was developing his Zeiss L and Standard they went other ways. The result was an uncompromised instrument, made from the best materials, of highest precision and with some very unknown features. For instance you would not find a substage on this stand. The condensers fit with a clever designed bayonet in the subtable. On the condensor a level permits lifting the condenser for 0,8 millimeter. This only for correcting for the thickness of the glass of the slide. The bayonet centers the condenser and I was able to get a sharp projected image of the field diaphragm in all specimens. Mind you: sixty years after the W left the factory!


The substage stageholder blocks the stage in use with one knob. So changing is easy, tolerances are zero.


Fit of the round sliding stage.


Sliding stage with its immersion plate. It works great if you use the right grease to slow down its movements.


The square stage turns around 270 degrees. Again a charm, for you can navigate through your specimen by turning table and knob. This picture has been made to show you a real Carl Zeiss logos.

The Opton designers (this article is a tribute to them) followed the sound L-armdesign of the prewar Zeiss L-stands and changed, like Kurt Mitchel, to one axis focusing on the table. There ends the analogy with the Zeiss Standard and the L and for good reason for the indecent love in those Mitchel-instruments for round curves has a lot of drawbacks in terms of stability and making room for accessories.

 The Opton is not blessed with a great range of accessoires. You have to do it with a fixed revolver for four objectives, interchangeable condensers (darkfield to), an enlargement changer with a Bertrand lens for phase plates alignment and some accessory camera equipment, a filterslot on the illuminator. It is clear: the genial designers wanted a microscope for brightfield and phase contrast and if you want epi, fluorescence or differential interference contrast go to our StepMother.

dsc_8067.jpg Universal condensor 1.30 with three phase plates and slider for oblique illumination.

dsc_8068.jpg dsc_8069.jpg Brightfield condensor 0.90.


If this is a sound idea for the small factory had no means to build more or because a limited arsenal of build-on things leads to more precision in the basic instrument I don’t know. I tend to think simplicity works. Fact is that this microscope is of the highest precision I ever saw and for instance the drawbacks in precision and ease of use in the Leitz Ortholux and Orthoplan are to trace back to the box of building blocks it is.

And the W shows tolerances zero. I had two on my desk (they say only five sold in the Netherlands) and was flubbergasted noticing that on the one a given point in a specimen was after copying the vernierscales on the other exactly X. Hold your breath.

dsc_8065.jpg dsc_8064.jpg Binocular tube of unusual design.

Mat hatter

First thing you notice is the most unusual design of the binocular tube. This ‘top hat’,  as the thing was quickly nicknamed, maintains under all circumstances the mechanical 160 mm tubelength. The design of this tube seems to exclude a photoport, but for making pictures they provided a beamsplitter with a laterally offset tube. There is also a straight monotube to mount a camera. A third tube on the top hat would have asked for a most complicated design of sliding prisms and swing out/in relaylenses, etc. So I think the designers did not even think about building it. Besides that Zeiss West produced already a great focusing telescope system on which could be mounted different types of camera’s. That one could be mounted on the supplied Orton monotube, so why introduce a thing that brings in risks for the imagequality. And certainly should not be bought by anybody. I had not a chance to test the beamsplitter.

The binocular tube has a remarkeble feature I discovered lately. On turning the right pipe for adjusting your personal pupil-to-pupil distance both pipes are out of their horizontal line. To correct this one can turn the whole upperplate of the binocular tube. Doing this I discovered another thing and that was that both my eyes are not in an exact horizontal line.  Conquering the deviation with the tube I believe this services tireless observation. Great for the analyst who had to observe hundreds of say bloodsmears on a day and great for me sitting besides my pond and observing for long periods all little things.

Yes, I intend to equip the illuminator with a led and are breeding on ways to do it without modifying the bulbholder.

dsc_8063.jpg dsc_8061.jpg dsc_8075.jpg 

The illuminator can slide on its foot which is a great way to center the filament.  This slider is metal but in the first instruments made of glass. The bulb is factory precentered.

Köhler is watching you

A sign with glowing capitals HERR DOKTOR KÖHLER IS WATCHING YOU was erected in the atelier I suppose for I never encountered a microscope on which with a light touch of the finger you can achieve total Köhlerlight. That thanks to the precentered 6V bulb, swing in groundglass positioned between collector and bulb (no noise in the image), precentered condensers (only a hammer will decenter them), and a most sophisticated illuminator. Well, it is covered with real leather, but that is not what I mean. The mirror in it is surface coated, no double filament projections.

On the phase condensor are two centering screws for each phase plate. In the original design the pair of centering screws were of different ‘feel’. On ‘my’ condensor they are the same, presumably because this instrument is one of the latest. On both condensers the diaphragms has no lever but a small hoop which is difficult to fiddle. In the big condensor you can obtain oblique illumination. Great.

dsc_8074.jpg dsc_8072.jpg 

The Plan 40x is fitted with a lock which makes (for safety reasons) the objective shorter. Not in the picture and never seen a dry achromatic objective 63x/0.9 with correctioncollar. (Seen it from Zeiss West and it is a most usefull objective for those who hate fiddling with immersion oil.)

This stand deserves the best optics and they are. The plan achromats 2,5x and 40x are even plan combined with widefield eyepieces. The phase 40x and 100x objectives bring the most undisturbed, clean phase images I ever saw, of course in combination with the supplied monochrome filter. I think those objectives surpass Leitz phase achromats of the same epoch. All objectives are of the highest correction and you don’t feel the need for fluorites. In other words, if you don’t intend to make colour pictures those are the things to use. Of course no comments on sharpness, and vivid bright images with not a trace of analogue artefacts.

The table is marked Carl Zeiss as is the binocular tube. That makes me believe this instrument is one of the latest marketed. In 1948 Opton went fully to Zeiss and production of the W gradually finished.  Zeiss West could not claim ‘we make the two best microscopesystems in the world’, but murder in the first degree of the W is a shame for everybody who wants the best. And the W is the best. Working with it is a delight and a honour. The W is the prima ballerina on my desk.


Of course because there are no spare bulbs to find I like to build in a led. Because the W is promoted working horse I feel I  have the right to do that. And it will not be that difficult to replace the bulbholder, saving the original piece of bad plastic. And by the way no more plastic to find in this instrument.

Factory numbers

For those who will be able to tell more of this instrument I give the factorynumbers of the different parts: Carl Zeiss stage 204533, Carl Zeiss tube 201533. Everything else is Zeiss Opton: Plan 2,5x 183011, Plan 40x 226327, achromat 10x 118911, phase 40x  226327, phase 100x 210355, condensor 0.9 218552, universal condensor 1.25 207240. The stand self bears no number and rests on three little cork rounds. A small detail which tells of the love for their trade of the designers.


Thanks to Mike Samworth of Britain, Secretary of the Postal Microscope Society who draw my attention to some literature about the ‘Arbeits- und Forschungs-Mikroskop Stativ W’.

Les folies de Leitz?

Posted by janvangelderen on January 10, 2007


Did not believe my eyes on seeing this rather frivolous trademark on a piece of junk which was sold to me as a genuine Leitz. Of course it is not. It is a fake brought on the market by some workshop which took people for a ride. The funny thing is that what was undamaged on the instrument showed a good piece of instrument makers skill. So why? Anybody out there who can put things in a different way, let him or her speak.


We could never blame Leitz for being frivolous. Once they came near and that was in a pr-picture from a lady dancing on a stand. That was in 1988.  And contrary to popular believe ( the original Leitz logo from 1913 is not derived from the design of a photographic objective, but from the section plane of their bicentric mirror condensor for darkfield. The Leica camera was introduced on the Leipziger Messe in 1925.

LED. New lights for old Leitz microscopes

Posted by janvangelderen on October 25, 2006

By Laurent Delvoye


LED makes exellent light for Diavert. 

In the last few years Light Emitting Diodes (LED´s) have been perfected to the point that their application for general lighting purposes has become a reality. Not only their luminosity has enormously increased, but they are also available in a broad range of colours, including white and near-UV. Those properties make them of interest for the microscopist.

Other desirable properties are: low power consumption und thus low heat generation, their long working life and the fact that on dimming the colour of the light remains constant. After reading some articles in Miscape on the subject ( I decided to make a LED illumination as an experimental prototype for my Leitz Orthoplan. This first attempt proved to be very succesful, so soon two more were constructed, one for my Ortholux and one for my Diavert. Thes two have replaced the original illuminations.

Contruction of the prototype

The LED was ordered on line at This on-line shop stocks nearly all the types on today’s market. On this website datasheets and other important information is available. After some browsing I ordered the Prolight Power 3 Watt white type. Within three days it arrived. Construction could start. In my scrapbox I I found the Leitz connector ring, a tube for the lampbody and a simple focussing mechanism with the condensor lens still in.

Putting them together was relatively simple.  From a sheet of PVC (1 cm thick) I cut a with a jigsaw a few connecting rings., filed and sanded untill the inner- and outerdiameters  fitted the parts to be connected. There were holes drilled and tapped in the material. The focusing part was assembled with lampbody using M3 screws.  See figures 1a, 1b.



The LED was fastened was fasetened with two M3 screws with nylon washers (beware of short circuit!)  on a suitable cooler. A small amount of heat-sink grease was applied between LED and cooler. Although the total heat production is small, locally the temperature in the LED is high enough to require cooling. In turn, the LED-cooler assembly was mounted on the bottom of a tin can with a long M-3 screw. In the bottomplate of the lampbody I driled an oversized hole. With two coins and two nuts a primitive but effective centering mechanism was realized. See figures 2a, 2b.



On soldering the wires on the LED care should be taken with the polarity. To avoid problems a red wire is connected with ‘ +  ‘  and a blue with ‘ – ‘. Use a low Watt soldering iron – a 15W is okay. A 2 Ohm/2W resistor is soldered directly to the LED. A 2500 mA 5 V constant current adapter was stripped from its outer casing, its output ‘ + ‘ wire connected in series with a 100 Ohm wire-wound potentiometer. Put together in a plastic mounting box it makes a fine power reguylator for the LED. There is enough light for normal microscopy. Low power darkfield and phase contrast viewing are possible. For the latter a green 3W LED is recommended. Then no filtering of the 3W white LED is required, with the lost of light that goed with filtering. From the beginning this illumination worked so fine that I ever used it since.


And this is how it works on the Orthoplan.

Construction of LED illumination for the Orthoplan and the Diavert

As the foregoing LED illumination was mainly constructed from scrap, here I faced a different situation being reluctant to modify the existing lampholders of bothe microscopes. So I decided to use the defective lamps as a base for the LED’s. For that I wrapped them in a paper towel and crushed the bulbs gently in a vice. The interiors remained intact. The two wires, that spun the tungsten wire were clipped to the proper size and gently sanding with fine sanding paper to remove any insulating material. After establishing with a multimeter the polarity, red and blue wires were soldered resp. on the ‘ + ‘ and ‘ – ‘. For the Ortholux, the 1W LED-cooler combination was directly mounted on the lampbase with Marine-Tex, a two component filler material used in in boat repair. The same product for carbody work will probably work as well.

For the Diavert a narrow passage in the lamphouse posed a serious problem. Therefore as a heatsink a 10Ct Eurocoin was soldered on a piece of short 15 mm copper tubing. The 3W LED is mounted with two M2 screws, with M2 threads tapped directly into the coin. This was mounted in turn on the lampfitting with Marine-Texz. After some careful filing on the outer edges of the coin and the LED. It could pass the narrow ring and it fitted perfectly. Both illuminations perform splendidly! See figure 3.


An experiment with UV-LED’s

My friend Piet Houpt drew my attention to his fluorescence experiment with UV-LED exitation with marine algae. With autofluorescence, the performance is in general to weak. But with fluorochromes it can work. So I made an adapter with a small UV-LED for one of my Ploemopak attachments.  For coral skeletal selections it works. There is light! But barely so. We will have to wait until stronger UV-LED’s become available. In this respect RGB-LED’s are also interesting. In this type of LED three typoes of light can be seperately lit, in approximately the standard red-green-blue excitation of standard epifluorescence equipment.  So in principle a simple turn of a knob can change the excitation wavelenght.  See figure 4.

My experiences with the newly marketed LED Luxeon K2 are impressive. I managed to build one in an Orthoplan illuminator using a resistor 1 Ohm-2W for 5V DC. Perfect! The light is more halogen, not as blue as the Prolight 3W,  while giving twice the output. On using the Heine condensor there is now more than enough light.

NICHIA has announced a super DV/LED and when it becomes available I intend to build it in an old style Ploemopak. I’ll keep you posted.

Laurent Delvoye was trained as a medical biologist. His main interest in the biology of tropical corals. He wrote several publications on coral reproduction and tgheir light biology. Since he will retire soon as a biology teacher in high school, he will be able tot devote a larger part of his time to the subject of his interest.

Order your slides! The Postal Microscopical Society

Posted by janvangelderen on October 25, 2006

The Postal Microscopical Society was founded in 1873, with its principal objective, the circulation of boxes of microslides illustrating the work of members and/or that of professional mounters.This is still the main function of the Society. Members are organised into ‘Circuits’. Boxes of microslides are circulated, accompanied by notebooks in which each recipient records his comments, criticism, and perhaps additional notes on the mounts themselves, before passing the box on to the next member of his ‘circuit’.


 Blastula, 8 cells, slide and picture Jan van Gelderen.

Currently, boxes are despatched at four week intervals. Thus, each member receives roughly twelve boxes per year. As each box will normally contain 12 slides, each member has the opportunity to study many different microslides during the year. It is rare indeed to receive a box which does not provide a great deal of interest and enjoyment; often the difficulty is to part with it. Members are actively encouraged to participate, by making their own slides available for circulation, and this aspect is the ‘life blood’ of the Society. The members are mostly amateurs with an interest in the microscope and microscopy, so the subject matter varies greatly.

Panel of Experts
The essence of the Society is the friendly and helpful interchange of information. Help is offered to beginners and experts alike by the maintenance of a panel of experts with experience or specialised knowledge in particular fields. Thus, help is only a postage stamp/phone call/email away and the beginner has access to a mine of information.
Balsam Post
‘Balsam Post’ the Newsletter of the Society, is now published four times a year. Written by the members for the members, this is another source of advice, news, help and guidance. The aim is to provide information but without too much scientific jargon. PMS help is intended to be practical and helpful. There are currently many back issues which can be supplied and these alone provide a mine of reading and helpful information. All members are encouraged to write for Balsam Post on any subject allied to microscopy and natural history. The cost of publication is covered by the general funds of the Society so all members receive the current editions free, by post of course. A comprehensive index is now available.

Members have access to their own library of books on Microscopy and Natural History. The Librarian maintains the club stock of books which are available on request to members. The Society pays the postage out but the borrower is expected to pay the return postage. The Library also contains a number of videos covering the techniques of slide making which are available to members.
Meetings are held in May and October each year and the Annual general meeting is an opportunity to combine this with a general meeting and exhibition of microscopy. This is the only non postal function that can be arranged, for with members spread all over the
UK, it is, inevitably, impossible for all members to make the journey. It is appreciated that some members for various reasons, do not wish to participate in the slide circulation section of the Society. For those who wish to be associated, but just do not have the time, or for whatever other reason, do not wish to receive the boxes, an alternative ‘Off Circuit’ membership is available at a reduced fee. All the other facilities and advantages, including ‘Balsam Post’ are provided for these members.Subscriptions

Army binoculars in the Bleeker Museum

Posted by janvangelderen on July 6, 2006


Although not being a microscope or part I’m glad to present a new piece for the Bleeker Museum. It is a 6×30 army prism binoculars from the Fifties. 

It shows the excellent qualities for which miss Bleeker is known. The first thing literally meets the eye is the quality of the optics – and the precision the instrument has been built. Having observed birds for fifty years or more I call myself a judge on binoculars. Razor-sharp images of great contrast and excellent rendering of colours with an enormous definition.  Greatest quality: the rest in the images only obtained by Leitz at the time.

   dsc_6663.jpg  dsc_6664.jpg



Ultimate fieldtest is ‘Can I distinguish the glimmer in the black eyes of a black coot on great distance?’ Yes. From my balcony I observed that the European swift (Apus apus) has more shades in its feathers than you would think and I was able to distinguish adults from the newly born.

These binoculars are shaped to the hands of men, weigh 578 gram. Having to adjust the eyepieces separately was in the beginning a little cumbersome but worked well and of coarse this is the secret of the dust-free interior. And that would be nice for all prism binoculars: two (red) dry air nipples.

Thanks to mister G. Bernebeer from Groningen I can tell you something of the history of this binoculars. In prewar time the lady constructed a 6×24 binoculars. Some went into the army, some into the resistance. In wartime miss Bleeker worked secretly on the base of the 6×24 on a 6×30 and it is this one I present. Production was undergone after the liberation, this one produced in the new facilities in Zeist. It is not known how long the army used this type for NATO which Holland joined in February 1951 required different specifications. However, the graticule is NATO type.

The binoculars are numbered 21717. Further inscriptions are M.v.O (Ministerie van Oorlog = War Department), 603-N, Dr. C.E. Bleeker Zeist, MEDIBU 6×30. I’m most intrigued what could MEDIBU means. In- and outside comndition is very clean, only some vulcanite on one of the houses is brittle. The whole comes with a genuine leather case. This one marked ‘Prismakijker Bleeker 6×30’.
