Re: "Pol" objectives in macrophotography under non-polarized, incident light

Many thanks to Scarodactyl and Apochronaut. I have read also elsewhere that Zeiss Jena objectives require specific eyepieces (e.g. Epiplan + KPL), but in my case the videocamera or photocamera sensor will be placed at the "tube distance" from the objective (I shan't use infinity corrected objectives...

"Pol" objectives in macrophotography under non-polarized, incident light

Good afternoon, I would like to test a low-magnification microscope objective to take pictures in ordinary, incident light (foraminifera). On ebay I see that some objectives are marked as "Pol", so presumably they are made with the low-strain glass needed for use under polarized light. An example is...
