Gemstone refractometer
Description
Gem refractometer is the most important tool for measuring Gemstone, It's also the most powerful tool for identifying gems. It can measure the refractive index of the gemstone quickly and accurately. The other optical properties of the gems can be determined.
The index of refraction is a very important optical parameter, All kinds of gemstones can be measured according to the value of the refractive index. Different gemstones have a fixed index of refraction. According to this parameter, it is possible to judge whether a gem is a single axis crystal or a biaxial crystal and positive or negative phototaxis.
