Optical Path Seat Analysis of Fully Automatic Abbe Refractometer

The fully automatic Abbe refractometer is a new type of refractometer developed based on the fact that the refractometers on the market today have a single function and do not have the inconvenience of solid and liquid measurements. This fully automatic Abbe refractometer can measure the refractive index of transparent and translucent liquid materials as well as the refractive index of transparent solid materials. In this paper, the three-dimensional model of the automatic Abbe refractometer is established by using soildworks, and the finite element analysis of the key part of the optical path seat is carried out to understand the stress layout and deformation, optimize the structure of the optical path seat, and simplify the overall design of the product. As one of the important optical parameters of substances, the refractive index is also one of the physical constants. It can detect the optical properties, purity and performance of substances, and is more reliable than measuring the boiling point of substances. Abbe refractometers are commonly used in laboratories based on optical principles. Domestic Abbe refractometers are mainly used in the detection of liquid substances, and with the emergence of new materials, more and more fields have put forward new requirements for the measurement of the refractive index of substances, and the application range of traditional Abbe refractometers is no longer Can meet the needs of the market.
