2. Product parameter
3. Product feature and application
Large eyepiece, wide field of view, easier to read
Frosted aluminum alloy countertop, corrosion-resistant, easy to clean.
4. Fields of use
Gem Refractometer can measure the refractive index of gems non-destructively, quickly and accurately, and can determine other light characteristics of gems.
5. Product details
The working principle of the refractometer is based on total internal reflection. This instrument measures the critical angle of gemstones and directly converts the readings into refractive index values.
Conditions for total reflection:
1. The high refractive index prism of the refractometer must be an optically dense medium
2. The gemstone to be tested is a light sparse medium
3. The contact liquid makes a good optical contact between the prism and the gemstone to be tested.
