Abbe refractometer is an instrument that can measure the refractive index and average dispersion of transparent and translucent liquids or solids (of which transparent liquids are mainly measured)
If a thermostat is connected to the instrument, the refractive index can be measured at a temperature of 0℃-70℃.
Refractive index and average dispersion are one of the important optical constants of materials, which can be used to understand the optical properties, purity, and dispersion of materials.
Application
This instrument can measure the mass fraction of sucrose solution (Birx) (0-95%, equivalent to a refractive index of 1.333-1.531).
Therefore, the scope of use of this instrument is very wide, and it is one of the indispensable common equipment in the petroleum industry, oil industry, pharmaceutical industry, paint industry, food industry, daily chemical industry, sugar industry, and geological survey and other related factories, schools and related scientific research units. One.

How does an Abbe refractometer work?
Abbe refractometer working principle is based on critical angle. … Light enters sample from the illuminating prism, gets refracted at critical angle at the bottom surface of measuring prism, and then the telescope is used to measure position of the border between bright and light areas.
