Although hard to find, there were both oil and glycerin immersion 63X N.A. 1.0 planchromat objectives out of the Reichert infinity R.M.S. D.I.N. production. There was not a dry 63X to my knowledge but they did make some objectives in the late 80's , probably for the Diavar 2 that surprise me when I come across them. There was also a 40X 1.0 oil planapo. Using one of those with 15X eyepieces has proven to be a better option than the 63X glycerin planachro, in my experience.
You underestimate the quality of the Reichert D.I.N. infinity objectives. Unless you have some post 2005 manufacture 100X planapo objectives kicking around from Zeiss,Leica, Nikon or Olympus, you haven't used one as good and it will even give them a run for their money. Yes, it has an iris. All of the objectives out of that program, with an N.A. over .70 were fitted with an iris. The design is very good. I have never seen one that was stuck or stiff and I have had I think 7 maybe 8 of them in my hands.PeteM wrote: ↑Tue Jan 28, 2020 11:49 pmThe Reichert would likely be somewhat compatible, but with a few things to know:
- It will require an adapter to go from RMS to 25mm thread to fit your DMLS.
- It won't be parfocal -- and will run into the slide if you forget to lower the stage every time you rotate this objective around.
- It's an older generation and won't likely have the more modern coatings and good contrast even compared to your basic C plan achro objectives.
- Judging from the screw on the knurled collar, this objective may have some sort of adjustment (cover slip? iris?) - those are often stuck in older objectives
The image and the vibrations are magnified a lot, so some movement under force in normal. It should behave like this: The stronger you press, the further it moves. If it rattles back and forth in a certain range without any real force there is something loose or needs at least a bit of dampening grease.
