Dear Member of this Group,

I know that Zeiss Objectives should be matched with Zeiss oculars.

There are some uncertainties which remain.

What ocular would best match a Zeiss Apo objective 40x/0.95 , dry
with correction for coverglass, 160 mm tubus length?

Would Nikon oculars made for the S-type scopes be an adequate
match?

I would appreciate any answers.

G.R.

Gee, the Nikon is probably the worst choice. The idea of the CFI, Chrome
Free, 160mm line was to correct a lot of chromatic problems in the
objective, not the eyepiece. This is a bit different from the way Carl
Zeiss and the rest do it. If you have a Nikon their great, everything
else, not so good.

In general the best Zeiss eyepieces are the Kpl ones, they were well
designed and made. However there is a possiblity the they can seperate
from the outside edge in, be carefull if you see a circular pattern on a
Kpl. Don't buy or use the plastic CPL (Cheap Plastic Lenses) eyepieces, a
poor design the Zeiss works came up with to save money.

Thanks,

If you get the old Kpl ones with the 2mm lip sticking out around the top,
it's just right for machining in threads for the Coolpix 9XX digital
cameras. 10x works but I recommend 8x if available.
