Re: Nikon CFN Fluor / Planapo 100 160/0.17

BR, John

Re: Nikon CFN Fluor / Planapo 100 160/0.17

Oddly enough, I am moving to the Olympus short-barrel PlanApos. I lucked upon a Vanox AH with DIC for a great price, and started to collect short-barrel PlanApos mostly because I was interested to see if the DIC would work better with objectives from the same era than with my Nikon CFs. Plus they p...

But there are also some generic Chinese 10x/22 eyepieces that perform really well with Nikon CF objectives.
Do you still have a note of the source or the generic description to hand please?

Thanks

Re: Even DF illumination for 4x objective

The Olympus condenser dovetail is slightly bigger than the Nikon one. It is definitely possible to use Nikon condensers on Olympus microscopes; I used a Nikon dark-ground condenser on my BH-2 until I found a cheap Olympus one. It may not be possible to use Olympus condensers on Nikon microscopes, I...

Re: Infinity Microscope Objectives designed to 100mm tube lens??

Hi Lou I have been looking around and talking about getting a 20x for APS-C on a Canon M6M2 using a camera tube lens at infinity 200mm. Whilst browsing a bit I came across a 10x QV which was engraved with f=100 with the thought that I could push it up to 20X on 200mm. I hope that my musing is still ...
