@anselmschueler The images were taken using a Polarizer over the light source to produce Plane Polarized Light which enters the sample thin section. Then above the sample is the Analyzer which can be rotated. "Cross" Polarized Light is achieved by rotating the Analyzer to 90 degrees (the white background changes to black).
