Dichroscopes are used to examine transparent stones. Depending on how the light rays differ in color, the object can be assigned certain properties with regard to its crystal structure. Our dichroscopes display the material brightly and sharply. The device works via a calcite crystal, the light coming from the stone is split into two adjacent, perpendicularly polarized beams. The device is particularly useful for stones with only weak pleochroism.
