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 0.007RI index units. With covering the full range from 1.30 to 2.99RI, 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. For More Information Please Logon http://goo.gl/jtH3xE

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 0.007RI index units. With covering the full
range from 1.30 to 2.99RI, 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.
