WebA gem's crystalline structure largely determines whether it's non-pleochroic, dichroic, or trichroic. That structure affects how light passes through the material. Light may be polarized and absorbed differently along different paths, which may affect the colors we see. WebLike so: Fig. 1: Dichroic mirrors reflect part of the light and only transmit emission light of specific wavelengths. BMG LABTECH’s monochromator-based microplate readers use linear variable dichroic mirrors, while the Optic Modules, used with the PHERAstar FSX contain fixed dichroic mirrors to suit the requirements of a particular assay.
