1.Gem Refractometer 2.1.30-1.81 nD 3.Internal LED illumination 4.Laboratory, Gemology 5.Polarizing filter

Equip with LED light Gemological Refractometer  

This model is a compact refractometer with built in LED illumination for the determination of the refrctive index,quality control and categorization of gemstones.

Each gem has a typcal refractive index due to its chemical composition and crystallization structure. The gem refractometer can observe the optical properties and the structure of a gemstone.Through the parameters you can judge whether the gem is and anisotropic stone or isotropic stone. The stone needs a flat and polished facet. contact liquid(RI Fluid) is also needed when testing.
