Leitz Heine condenser and Orthoplan

#1 Post by Rainowman » Thu Sep 12, 2019 10:58 am

I have the opportunity to buy a boxed leitz Heine condenser set, with the following eyepieces;
Pv 10/0.25 f.p.- O k
Pv 25/0.05
Pv Apo L 40/0.70 n
Pv Fl Oe 70/1.15
These eyepieces are mounted on a rotating objective carrier that I think fits the early black Ortholux.
My question is will they transfer onto and be compatible with my standard x1 Orthoplan nosepiece.

Has anyone any experience of using this system on an Orthoplan.

Hi,

Probably not. The PV series were made specifically for the Heine
back in the day when Leitz was using 35mm parafocal objectives.
Mount a 10x and see if you have at least another 5 mm of stage
travel. Better yet, wait for one of the Orthoplan users to chime
in.

Have fun.

Hi,
look here: https://www.mikroskopie-forum.de/index. ... ic=26063.0
It was actually a parfocal length of 37mm. Therer were adapters called "PLEZY" that added 8mm lenth and had a weak lens to correct for the changed tube lenght.
Perhaps this is more for the collector today.
