Description

Hand-held dichroscope

Dichroscopes are used for the investigation of 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 polarised beams. The device is particularly helpful for stones with only weakly pronounced pleochroism.

Technical details at a glance:

■ With calcite crystal
■ Viewing window: Ø 15 mm
