Product Description

The Digital Gem Refractometer is a good optical instrument which will give a reading of the refractive index of a clean, flat, well-polished facet to reproducibility of 0.**7RI index units. With covering the full range from 1.*0 to 2.*9RI, It is an ideal instrument to recognize the gem stones. The importance is that it can test the gem stones without requiring ANY messy, damaging contact oil.

Refractive index is one of most important optical parameter. Gloss of gem can be estimated by the parameter. The kinds of gem can be precisely determined in accordance with the measured value of refractive index because every kind of gem has its natural refractive. Besides, index of double refraction can be also measured. Through the parameter you can judge whether a gem is uniaxial or biaxial photopositive or photonegative. The weiber digital gem refractometer can observe the optical properties and the structure of a gemstone by judging whether the gem is anisotropic stone or isotropic stone. Moreover the equipment is extremely portable and cost effective.
