Moss

Post by Olympusman »

A few weeks ago, after almost twenty years of faithful service, my primary microscope became impossible to deal with. I bought a trinocular from ShopGoodwill.com for $150 as a replacement and as a result have had to redesign my microscope lab by switching around a half dozen condensers I has lying around, playing with projection lenses (aiming to use my Olympus NFKs) and tewsting various camera mounts to isolate the cameras frokm the scopes. Just about there.

This is a moss from a shaded area of gravel in my yard.

It looks very promising, a bit of peripheral CA bit beautiful and detailed photos. I assume the NFKs are matched with Olynpus objectives? I'm curious to see your loadout if you ever want to make an equipment thread--goodwill sells a surprising number of interesting microscopes

I'm sorry to hear about the old scope. :(

What does "impossible to deal with" mean?

Impossible to deal with ...
Primarily, the stage crapped out. Its action was no longer smooth and I didn't want to replace it (and didn't have another stage lying around). The other big one was that with 40X objectives and higher two dark blobs appeared at approximately the 8:30 position in the field of view. Some kind of back focus issue, but never did find the problem. I had broken the scope down repeatedly to find the cause and finally gave up. I salvaged as much as I could from it (trinoc head, condenser). I have three scopes in my lab area, plus a metallurgival scope in my office. Besides parfocality, on each scope I test all the objectives with a micrometer slide for sharpness, contrast and astigmatism.
One interesting thing about NFKs is that they require the photo tube on a trinoc head to be shorter than provided to hit parfocality, so on one scope I had to mill the tube length down.

Scarodactyl evinced an interest in the replacement process, so I will post a short article in Equipment Discussions.
