The Plan Neofluars are infinity corrected. The NPL Fluotar sounds
like an infinity phase objective. The 63X PlanAPO is 160mm tube
length. This is probably the best 160mm objective Zeiss ever made.
It is awesome! I had one on an Oly BH2 and it was terrific.

I don't know what the 100X objectives are.

Using low power objectives requires a low power condenser. So for
these infinity objectives, you need an infinity system and low power
condenser. A difficult situation.
