The Polyvar is the second iiteration of the concept. The first was the Univar of which only about 500 were made but the important thing is that the objective complement that was originally manufactured for the Univar is also relavent to the Polyvar, as well as objectives later manufactured for other more modest models.. I had not seen a 10 X 0.32 iK objective before, only 10X 0.30, and only as a planapo. From the list suppplied by Michael G it seems that the 10X 0.32 IK is also a planapo, yet yours is not marked as such?
Additional to that list there are also the following coverslip corrected optics to my knowledge., some of which were also listed for the Diavar 2, the Polylite etc.
2X .08 plan fl apo
4X .13 planapo
10X .30 planfl apo
40X .70 planfl apo
63X 1.00 plan glyz. im. ( planachromat)
63X 1.00 plan oel . im. (planachromat)
100X 1.25 plan glyz.im. (planachromat)
100X 1.30 planfl apo oel im.
Reichert produced a whole range of objectives in the 80's called planfl apo. I list the only coverslip corrected ones I have actually seen above. There may have been others.
The original concept from the start was for all objectives with an N.A. over .75 to have been equipped with an iris. Later, they departed from that as the infinity corrected design principle was extended to more economical stands such as the Diavar 2 . Across the pond when AO extended it's objective parfocality to 45mm, three of the planfl apos were just marked planfl and offered for the Microstar IV and Diastar.
Additionally, there were phase objectives with higher colour correction and I believe anoptral versions in planachromat format too, although those may have been limited to the early days of Reichert's infinity corrected program. I have not seen anoptral objectives for the Univar or Polyvar, just heard about them. There is a forum member who knows something about that. Perhaps he will chip in.
The higher colour corrected phase objectives I know of are.
40X .70 planfluor phase. Odd objective with a very small, thin annulus. I have been told that it did not produce phase in a Univar but I was able to get DF/phase by pairing it with the 100X diaphragm in a Diastar. DF/phase/oblique even. I am using Reichert Austria phase objectives otherwise successfully in a Diastar, so it seems there is optical continuity between it and the Polyvar mostly.
40X 1.0 planapo oil phase
100X 1.30 planfl apo oil phase
100X 1.32 planapo oil phase
Presumahly there are 10X and 25X planapo phase versions too. Not seen them.
That fleshes out the objective options for it mostly.
The f.o.v. is 24mm. There was also a 16X W.P.K. eyepiece too.
