Gemmological Refractometer

In the various observation method of gem stone, the measurement of refractive index is the most reliable one for the identification of gem stone. Designed in compact, provided of shield cover to make measurement part to dark room and measured with day light. this instrument identifies gems accurately with apeed and ease at everywhere. Also, accessaried with polarizing filter, birefringence dispersion of gems can be observed and measured. Provided with wide measuring range of refractive index from nD 1.30 to 1.81, the most of gem stone can be observed and measured.
