I don't think it is possible to change a finite optics microscope to infinity-corrected. You would be better off getting higher-grade finite optics for your Ortholux 2. Main advantage of infinity systems is ability to insert additional attachments into infinity space. Being a beginner, it is not som...

This is sad - I found Raf through Ebay, and we designed an adapter for Olympus stereo microscope objectives to attach to Leica MS/MZ series microscopes - I use one of these adapters now.
Without Ebay, I would not find Raf...

Do you know what is going on with Raf? He removed all his items from Ebay. I worked with Raf earlier on adapter to mount Olympus SZH/SZX lenses on Leica MS/MZ/M microscopes with M50xPh3 thread, like Mz6 that I use: https://www.ebay.com/itm/256248894585?hash=item3ba99fd479:g:WIcAAOSwCaVlIxoG&amdata=e...

I use Olympus and Meiji objectives on my Leica MZ6. This adapter works great: https://www.ebay.com/itm/256248894585?hash=item3ba99fd479:g:WIcAAOSwCaVlIxoG&amdata=enc%3AAQAIAAAA8H417YQEoL9Gq7zULOqQ2djNvJils7JUTYgKcJSdOGJuEPSw1j2Iw24abOXaSIzGF3mkLKboSBtkSET%2FaBPWtVr528DdQV9y7TxZoRzVvjEMoCJSZLrdXSqjf...

I am down to just two: Olympus BX-45 with some nice objectives, and Leica MZ6, which I use for working on electronics. May replace the BX45 with something more compact, but still high quality...

Wow! No kidding... What are they smocking there at Leica? It's not just THEIR ugliest yet, it the ugliest of ALL stereo microscopes! They just made a bar of soap shaped like their A60 educational model, and washed their hands a few times...

Wow, great job!

I did not try phase contrast on CX, but there is a Phase-contrast condenser CX-PCD, or Simple phase contrast attachments CX-PH1, 2, 3 for the standard Abbe condenser. All of them are hard to find on the used market.

It's a great microscope, it is fully compatible with Olympus UIS/UIS2 optics, so you can mount any infinity-corrected Olympus objective and any head from BX series, and enjoy the best image quality and ergonomics.

I was looking at this earlier too. The dic doesn't look amazing, not very even at all. I bet the spacer is 3d printed as well. When I look closer at the photos provided, the spacer does not show that rough layered surface like other 3d-printed parts. Also, you can 3d-print the raiser's body, but no...

Somebody (not me) made an interesting adaptation of DIC to Olympus BX40 using 3D printing: https://www.ebay.com/itm/225568562700?hash=item3484ef1e0c:g:2uEAAOSwOkRkWFer&amdata=enc%3AAQAIAAAA0FnyT1UwwC1BayvIv5CXfdi3OIW5maKFWYs2m4UXfRryzejEsgadzy%2FLDATVx9qVxzLba5XVpcgKu%2FcsVSbwpjywAUyCmtSEUp2gwHn%2F4...

Are condensers for Olympus BH (finite 160mm system) and BX (infinity corrected) the same? They look the same, and mounting dovetail is the same 47mm, so BH condenser fits into BX holder. But are they optically identical - would a BH Achromat Aplanat 1.4 condenser perform the same as new BX U-AAC whe...

An excellent scope, perhaps, more than I needed, so I sold it about a year ago. Yes, DF PLFL 1.6X PF is a great objective, I had it mounted on the revolving SZX-2RE nosepiece together with DF PLFL 0.5X PF - highly recommended! This combination will cover magnification range from 3.5x to 144x without...

I just had a few minutes to try the Meiji condenser on Olympus BX40 microscope - it will NOT focus on the field diaphragm opening!
Meiji condenser worked great (better than Olympus one) on finite Olympus scopes I tried it with before.
Just something to be aware off. Sorry for the confusion!

There are a lot of Nikon labophot 2 with an obsolete dead PSU. That unit looks like it could be used but I suspect from the asking price of a bulb it wouldn't be cost effective. It's not the same PCB but the ¼ watt resistor size is recent so the components are unlikely to be obsolete. This is a sim...

Is the PSU still available?

What do you mean by "available"?
It's a current model, so parts should be available from Meiji Techno.
They provide a Limited Lifetime warranty for their products, unfortunately, not transferable to 2nd owners: https://meijitechno.com/warranty/

Meiji Abbe 1.25 condenser provides better contrast than Olympus equivalent – when you close the light source’s field diaphragm and focus the condenser, the outer gray area is noticeably darker in Meiji than in Olympus. Meiji condenser’s dovetail diameter is 45mm vs. Olympus 47mm, so I can mount and ...

I have this microscope for a couple of years. It’s made by Meiji Techno, the 3rd Japanese microscope manufacturer, that is “vertically integrated” – meaning that they make almost everything at their own factory in Japan. Meiji is better known for their stereo microscopes – favored by jewelers, engra...

Part of the problem with Kohler is it's not competitive to produce.
I was wondering about getting a 3D printer.

Prusa just announced the new MK4 printer - expect plenty of Prusa i3 Mk1 - Mk3's on the used market.

I'd still be interested in with and without images. Here you are, with the 40x objective: "Open" diaphragm: open.jpg "Closed": closed.jpg This is exactly what I was trying to achieve with this contraption: reduce the size of the illuminated circle on the specimen to reduce the stray light and impro...

Well, they are just plain wrong. It seems that Evident is on a campaign to justify their existence as well as appeal to the mass market. It is hard to understand why they would title that little 6 step blurb " How to align Köhler illumination in 6 simple steps" because they are misguiding those tha...

I'm not sure that I am following you directly but Köhler illumination is simply a method of defocusing the illumination source at the field diaphragm plane. It has nothing to do with centering anything or providing limiting apertures anywhere in the system. Those are entirely separate controls one ...

For a complete, integrated, and finished solution, this is pretty damn sexy! Well done! Did you calculate the various apertures or come to them through trial and error? Thanks! As I stated above, to find the diaphragm’s diameters for my objectives, I placed a brightly lit ruler in the same plane wh...

It must be said that's a good effort. Poor and 3D printer is all relative. I don't know enough to say if it's effectively a filter patch in that position but I'm sure it offers lighting effects that could be interesting. Maybe some with and without images would be good if possible? A very good 3d p...

Some basic microscopes, like Olympus CX23 I am playing with now, are not equipped with Kohler illumination, thus not being able to achieve better contrast and clarity Kohler illumination provides. One of my previous microscopes, Olympus CH2, also didn’t have Kohler illumination, and I made the same ...

Why do the CX objectives have optical parts that go into the nose? Is this on purpose to keep people from using the E Plans on non-student scopes or is there a technical reason? An interesting question... I don't have another Olympus 100x oil objective (don't have a need for immersion), but that's ...

I’ve got this scope by sheer serendipity for free, but I had to spend two days cleaning it from some semi-hard goo and repairing it. Now it is in pristine shape, more or less. Somebody used this glue-like compound liberally on the stage, and it leaked into everything below it (condenser, light sourc...

I’ve got on my work bench an Olympus CX23 microscope. This is a current model, positioned as an educational microscope for schools and colleges. I decided to compare it to a laboratory-grade microscope (BX40) and see what you would sacrifice if you opted for a CX23 instead. Probably the first thing ...

A better-corrected condenser should help the color fringing you're seeing. As Phil suggests, the Olympus .90 swing-away condenser would be a good choice. The lack of contrast may be partly an issue of the objectives if they scatter light excessively. Are they Olympus Plan or UPlanFl and in good sha...
