Again I’m getting good DIC with a Leitz 100x/1.32 Oel P objective with a Zeiss first version condenser (prism III) and the Zeiss DIC/analyzer Slider II.
My Zeiss PK 2.5x photo eyepiece crops the field of view on the camera sensor, so this is pretty much at the limit of resolution of this optic when I don’t oil the condenser to the slide. A simple brightfield image does show the reticulation, but here DIC brings out more surface contrast due to the relief effect of DIC.
