- Essential Gemstone Identification Tool: The Gemstone Refractometer is a crucial instrument for gem identification, allowing for non-destructive, quick, and accurate measurement of the refractive index, with a test range of 1.300-3.000.
- Advanced Structure: This refractometer features high-sensitivity sensors, intelligent electronic components, and a clear LCD screen for easy reading and operation.
- Working Principle: Utilizing the principle of total internal reflection, this refractometer measures the refractive index—an essential optical parameter to characterize gemstones and determine their properties.
- User-Friendly Test Method: No refractive oil is needed! Simply place the measuring surface of the gem close to the platform to obtain measurements. This allows you to identify whether the gem is a uniaxial or biaxial crystal.
- Versatile Application: Quickly and accurately identify single and double gemstones, including moissanite, diamonds, and colored gemstones. This tool is specifically designed for measuring the refractive index of various gemstones and solid materials.
