【Gemstone Refractometer】It is the most important tool for gem identification, and can measure the refractive index value of gemstones non-destructively, quickly and accurately. Refractive index test range 1.300-3.000

【Structure】Gem Refractometer is mainly composed of high-sensitivity sensors, intelligent electronic devices, and LCD screens

【Working Principle】The working principle of the refractometer is based on total internal reflection. The refractive index is a very important optical parameter, and the characteristics of gemstones can be determined based on this parameter

【Test Method】No refractive oil is required, just bring the sample's measuring surface close to the measuring platform to measure. Based on this parameter, you can determine whether the gem is a uniaxial crystal or a biaxial crystal.

【Application Function】Quickly and accurately identify single and double gemstones, moissanite/diamond/colored gemstones, designed for measuring the refractive index of gemstones and solid materials
