Descripción del producto
The refractive index is one of the most important optical parameters. The gloss of the 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 inherent refractive. Besides, the index of double refraction can be also measured. Through the parameter, you can judge whether a gem is uniaxial or biaxial photopositive, or photo negative.
The gemological refractometer is characterized by small volume and less weight. It is easy to carry. It is a popular instrument used in the jewelry market.
