Principle experiment of graphic interpretation refractometer

A refractometer is called a refractometer. It is mainly an instrument that uses light to detect the concentration of a liquid. It is used to detect the refractive index, birefringence, and optical properties, and the refractive index is an important physical constant of matter. The working principle of the refractometer is that when the light passes through a transparent medium and enters another transparent gold, the refraction is generated. This refraction is mainly formed by the different speeds in various media. The refractometer studied in this paper is mainly used in the determination of the refractive index of gems and jade. The refractometer can detect the refractive index and birefringence of gems and jade, and can also measure the positive and negative of axial and optical properties. It is an important tool for studying the optical properties of gems and jade. important equipment. The crystal optical properties of uniaxial crystal gems, such as refractive index, birefringence, and optical properties, are discussed from the experimental analysis, the principle of cross-beam instrument and crystal optics.
