My "new" Leitz Laborlux(?) POL circa 1960, 2 questions
Posted: Mon Sep 30, 2019 5:01 pm
Hi all, I bought this very nice scope to expand my hobby into petrography. I just set it up and centered the objectives and all is good so far!
I have 2 questions someone might be able to answer.
1) Red arrow in attached pic: this is the Bertrand lens control I believe; there seems to be 3 settings, in, out and "half-in"?. What is 3rd setting used for?
2) Blue arrow in attached pic; what is this slider/adjuster for? Seems to be related to the Bertrand lens (focus)?
Thanks in advance for any info.
