• ►【High-Quality Material, Safe and Durable】: The workbench surfaces of the gem refractometer is precisely crafted from hard aluminum alloy, which is not only scratch-resistant and wear-resistant but also provides stable and solid support, ensuring no shaking interference during precise testing. The power switch is made of high-quality ABS engineering plastic with a built-in triple insulation protection structure, which blocks potential electric leakage from the source
• ►【Scientific Principle, Accurate Foundation】: The core working principle of the instrument is based on the phenomenon of total internal reflection in optics. As a crucial optical characteristic parameter of gems, the refractive index is a key basis for distinguishing gem types and judging their physical properties. By accurately capturing this parameter, it can provide scientific and reliable theoretical support for gem identification
• ►【Professional Identification, Efficient and Precise】: As a core tool in the field of jewelry identification, it can realize non-destructive, rapid, and high-precision measurement of gem refractive index. The measurement range covers 1.300-3.000, which can meet the identification needs of most common gems and provide quantitative data support for identification results
• ►【Easy Operations, Comprehensive Functions】: No need for refractive oil; simply place the measuring surfaces of the gem sample close to the measuring platform to complete the refractive index measurement. Furthermore, it can judge whether the gem is a uniaxial crystal or biaxial crystal through the measured parameters, simplifying the operations process while enhancing the professionalism of identification
• ►【Wide Application, Strong Targeted Design】: Specifically designed for measuring the refractive index of gems and various solid materials, it can quickly and accurately identify single-crystal gems, double-crystal gems, diamonds, and various colored gems, etc. It is widely applicable to scenarios such as jewelry identification institutions, gem processing factories, and collection enthusiasts
