In Bragg Microscopy the sample is illuminated with white light under an angle Q to obtain a Bragg reflection in the direction of the observing microscope objective. In principle Bragg Microscopy is an inverted light scattering experiment. Crystals were observable if oriented properly to fulfill the Bragg condition. Crystals of identical color correspond to identical structure and orientation. It is a easy method to study the crystallization kinetics and morphology of oriented crystals.
