The Dikai table gem polariscope is made from quality materials with rotating glass polarizing filters at its top and in the base.
It has a built-in light and a slit in the base of the unit which allows it to be used as a light source for a refractometer and other gemological instruments.
This polariscope offers an efficient way of testing single or double refraction, optic character and pleochroism of transparent or translucent gems, either loose or mounted.
Optional stone holder and interference sphere can be purchased separately.
