Leica DM IL (searching for correct set up info)

Hi, I have a Leica DM IL (black print on the sides, no red decorations) and only an overhead light, type 090.131.001. Basically no lower lamp and no dichroic mirror in the base. The binocular head is the "Made by Leitz Portugal 512 821/20" with the eyepieces being Leitz PERIPLAN GF 10x/20 M. If that...

Olympus Objectives That Need NFK Relay Lens Correction

Olympus objectives now do not require any relay lens for fixing aberrations, like NFK X.X lens in the U-SPT tube. So Olympus has discontinued the U-SPT for BX/IX microscopes.

So what series identifiers indicate that a NFK relay lens should be there?

Thanks.

Can you send pictures of how the set screw was done. They seemed to have put in some type of brooch that would be interesting to see.

Re: Trinocular Modification for an Olympus CX31?

A single port with a camera that allows you to do video on your computer screen then some high res single shots would be the way I would go. I don't like eye pieces. They're a relic from the past. So instead of buying an expensive trinocular, buy a tube lens instead. For Olympus the part is the U-TL...

Universal Stage on a BX

This is a BX61 with the BX-RLAA brightfield/darkfield epi lifted up 3.5 inches to make room for a large objective and a Zeiss universal stage. So it looks like this could work, and unlike one article published which used a standard objective with too short of a working distance, the super long worki...

Zeiss AxioPlan 2 Stand Design Question

Hi,

Can the epi of a Zeiss AxioPlan 2 be detached from the main part of the stand like an Olympus BX41/51/61's epi/arm?

I want to put a spacer in between like I'm doing with a BX61. It would be great is Zeiss was also another possibility.

Thanks.

Re: WANTED Olympus intermediate polariser

If you have BH parts and want to hook them to BX, you could do what I did here: viewtopic.php?f=5&t=7327

If you scroll down you can see the CNC part that is work-in-progress right now. But the 3D print can work for a while.

Here's a challenge. In the Star Trek series Enterprise, Dr. Phlox has an inverted microscope in the second season's episode Dear Doctor.

What make is it?

Of course he's clearly done some mods. It can see DNA and there are no objectives.

Re: Patch Stops

Cool looking set. They probably are made from PLA since they look like they are 3D printed. 3D printings can have "stringing" which are little threads of plastic as the head switches from one part to the other. A file or sand paper can remove that. Also the crisscross pattern is the 3D head printing...
