They were not. You have to to take into account, that there were two
Zeiss Companies by then. Carl Zeiss, Oberkochen, West Germany, did not
make infinity corrected objectives by then for their trasmitted light
microscopes.
VEB Zeiss in Jena (German Democratic Republic), however, produced some
infinity corrected light objectives. These were not fluorite systems,
but achromats and apochromats.
At about that time or a bit later Zeiss
began to produce the Axioskop.
That was Carl Zeiss Oberkochen.
< This scope has not
been produced in some time. It was superceded by the
Axioskop 2 and now Axioskop 40 is on the market.
Questions:
How do the Plan-Neofluars of the late 80's and used on the
Axioskop compare to the ones now being sold? I assume
that these objectives can be used on the Axioskop 40,
no.
but do
they perform the same way?
No. In quality: yes. The first series of Plan-Neofluars cannot be
topped, not even by the new ones.
All PLAN-Neofluars are immersion (!) objectives, but they all can be
used with oil, glyzerin or water.
It may just be that the newer
Plan-Neofluars are better performers in some way when com-
pared to the the old ones. Does anybody have information on
this subject?
The nes ones are a tick better suited for fluoreszence and
polarisation, because they could be constructed with significant less
lenses.
