The gem polariscope is a non-destructive optical tool used to identify gemstone authenticity, distinguish between isotropic and anisotropic materials, and analyze optical properties such as refraction type, axiality, and optical sign.
Product Description:
The Gem Polariscope is a non-destructive optical instrument used to evaluate the internal optical properties of gemstones. It helps gemologists and appraisers quickly determine whether a gemstone is isotropic or anisotropic, and whether it exhibits single or double refraction. By analyzing the gemstone’s behavior under polarized light, users can identify the optical character, axiality, and overall authenticity of the sample without any physical contact—making it ideal for testing valuable or fragile stones.
Core Functions
- Identify whether a gemstone is singly or doubly refractive
- Distinguish isotropic vs. anisotropic materials
- Analyze optical character (positive/negative sign) and axiality (uniaxial/biaxial)
- Assist in the rapid identification of gemstone authenticity
The RHG-181 Gemstone Refractometer is a portable optical instrument designed to measure refractive indices from 1.30 to 1.81, enabling fast identification of gemstone types, differentiation between natural, synthetic, and treated stones, and analysis of optical properties such as birefringence and crystal orientation—making it a practical tool for jewelers, gem traders, and inspection agencies.
