This article mainly introduces a new type of gemstone refractometer based on Fresnel formula and optical fiber technology. A refractometer is a measuring instrument used for refractive index parameters, which is widely used in business, teaching, scientific research and related gemstone identification. The traditional refraction is designed based on total reflection. In principle, it is rarely used in the measurement range (N < L.81), requires contact with toxic solutions (diiodomethane, etc.), and has disadvantages such as inconvenience in interpretation. Refractive index, which is an important parameter characterizing the optical properties of various materials, including gemstones. The refractometer is the measuring instrument used for this parameter, and it plays a very important role in business, teaching, scientific research and related gemstone identification. The traditional refraction is designed based on total reflection. In principle, it is rarely used in the measurement range (N < L.81), requires contact with toxic solutions (diiodomethane, etc.), and has disadvantages such as inconvenience in interpretation. A few years ago, there was a new type of refraction at home and abroad, which was based on the Fresnel principle and the arrival of the refractive index value measured by the method of surface reflectance. It has a wide measuring range (up to 0.2990), is easy to operate, interprets useless toxic solutions, and has received attention, among other things.
