Re: Zeiss Photomicroscope III correction?

Question about the Zeiss Photomicroscope III: did this scope perform
correction in the eyepieces, or were the objectives already corrected?
It's 160mm tube length design, correct? I'm trying to analyze whether we
can just stick a digital sensor on the top and get a corrected image in
direct projection.

Zeiss corrects some problems in the eyepiece and some in the
objective, some are corrected in both.

In the case of the universal frame (Photomic, Universal, etc) there
was a tube lens place just above the nosepiece. This lens converted
the 160mm into an internal infinity corrected system. Since there
were no additions between the nosepiece and the two attachment pieces
on the beam splitter assembly the whole deal worked quite well.

Now the real question, what do you want to put were? Usually is you
wanted to put a simple camera on a universal you used the simple
trinocular tube. Never, ever shorten one of these, their outside
diameter is not constant. For correction you used an eyepiece,
usually. Using this system what worked on a Standard would work on a
universal. Zeiss was scared to have to many accesories, as if...
