I’m in for finding the opinions of the masters today!

Earlier this year I asked for microscope recommendations, to which I ended up with a Meiji GEMZ/BF-DF-5TR Gem BF/DF Trinocular Zoom Stereo System which has been such a fantastic scope. I would like to play around with some photomicrography, being very intrigued with inclusions. I was wondering if anyone could offer any recommendations on utilizing the trinocular aspect of this scope? Any mount and camera recommendations?

Also been kicking around getting a new UV light system and viewing cabinet. The uv light I have now is really better suited to minerals, it’s large and kind of a pain but it was affordable at the time and does do the job.

Thank you for any insight!

I use the UV cabinet available through Kassoy:

I purchase it a long time ago (30 years) and have replaced the actual light 3 times.

It is still going strong and I use it everyday. The cabinet is indestructible.

I'm glad to hear you like the Meiji. I don't have a specific camera recommendation, but once you've chosen a camera, you'll want to get a corresponding adapter ring. Meiji has camera adapter rings for many different camera brands that make it easy to attach a camera to the trinocular camera port.

For example, I use a T2-5 ring to attach a Nikon SLR camera directly onto the camera port (i.e., no lens at all between the camera and port).

You'll also need the correct photo tube and photo lens.

My setup is a GEMZ-5TR combined with a Nikon camera with 3/4 sensor, a D40 or D3300. The parts Meiji recommended me were the MA150/50 photoport and the 2.5x photo lens. But especially the lens needs to be fitted to your camera, so check with Meiji if you are unsure. That is what I did. :)

You'll need to fiddle around a bit with the length of the photo tube to make sure that the image is in focus for the camera at the same time as for your eyes. Also, be aware that you'll need to manually program all exposure parameters on your camera, e.g. the ISO. Only the 'M' program on the camera will probably work, at least on mine it's the only option...

Interesting. I don't use any tube or lens at all. I just thread the bare camera onto the mount.

Let me see if I can add some pictures...

First, the complete setup... The photo lens is invisible in the first picture as that sits inside the photo tube. We'll get there in the next pic...

Image

After removing the outer photo tube, we're left from top to bottom with the lens, the inner part of the photo tube, and the photo port itself.

Image

The lens is a cilinder that slides into the inner tube. Let's remove that as well.

Image

A picture from above with the lens back in place:

Image

Finally this is what the camera + nikon adapter + outer photo tube looks like:

Image

You made me curious how you manage without all this Brian... :) The other option is of course to use the camera lens and attach to one of the two oculars, but afaik that only works with point-and-shoot type camera's including smarthones, not with DSLR's...
