List of Reichert/Leica 45mm Parfocal Infinity RMS Objectives?

#1 Post by Zuul » Thu Jun 04, 2020 5:14 am

I believe I’m spoiled by P.S.Neeley’s encyclopedic collection of AO information. Is there any resource where one could find a reasonably complete list of the more modern 45mm parfocal Infinity RMS objectives sold as Reichert, Leica or otherwise for the Microstar IV, Diastar, ATC2000, etc?

If you search the archives, forum member "Apochronaut" has done several exhaustive listings and discussion of the AO/Reichert/Leica/Cambridge infinity objectives.

Apochronaut certainly knows more than anyone here about these objectives. I wasn't able to find a single post where they were all listed, though. I put together this table from all the sources i could gather. Hopefully it will be helpful to others. If anybody has additions or corrections, please let me know.

These are all the 45mm parfocal RMS objectives I’m aware of.

The Leica branded objectives were made for the ATC 2000 microscope which probably was already in the pipeline by the time the Leica name was chosen for the merger. It was a replacement for the 150 in the scholastic market. The Leica plan objectives that I have trialed are similar to the Reichert Neoplans. The phase objectives are optical versions of them except the 20X .50, which doesn't show up as a BF. It may be just a remarked 1733, since it would make a lot more sense to do that, than design a whole other objective.

The ATC 2000 phase objectives( 1750-53) don't exactly work in a 400 series microscope, the same way that the 400 series phase objectives (1742-45) and (1746-49) do. The background is more brownish and looks more like what one would expect of anoptral objectives. Those that I have looked at seem to have good resolution otherwise.
There is a planfluor 100X 1.32 w/iris. I have never seen or been able to figure out the cat. # for it.

Then there is also the whole rasher of objectives made between about 1972 and the late 90's for the Austrian Reichert microscopes., a bunch of plan, plan fluor, plan fluor apo( probably just a later name for the former) and planapo. These have their own Austrian cat.#'s and work well in the series 400 stands.
