Bertrand Lens

#1 Post by microb » Sat Sep 14, 2019 3:47 am


I would like to find easy to follow procedures with the simplest slides for example, and/or calibration targets to test a Bertrand lens set up for petrographic usage.

I have a granite thin section slide, polarizers, DIC, but none of the well known compensators. What do people in the field use as the simplest set up? What would be a good test? Could one for example focus on a polarized optic filter set up in some particular way and get some interesting Fourier patterns? What's a good reproducible test?

Any other usages for the same set up, please let me know.

Thanks in advance.
