Abbe refractometer is an instrument that can determine the refractive index and average dispersion of transparent, translucent liquid or solid (which is mainly to measure transparent liquid), if the instrument is connected to a thermostat, the refractive index can be measured within the temperature of 0~70 °C. The refractive index and average dispersion are one of the important optical constants of a substance, which can be used to understand the optical properties, purity and dispersion size of the substance. It can be used for the detection and analysis of sugar, pharmaceutical, beverage, petroleum, food, chemical industry production, scientific research and teaching departments. Its principle is: if the light enters the photophobic medium from the light-dense medium, the angle of incidence is less than the angle of refraction, changing the angle of incidence can make the refraction reach 90 °, the angle of incidence at this time is called the critical angle, and the instrument determines the refractive index based on the principle of determining the critical angle.
