Spectrophotometer testing device

Abstract

The invention discloses a spectrophotometer testing device which comprises a body for testing. The body is connected with a stabilized voltage power supply, and a power switch and a power indicator light are arranged on one side of the front end of the body. A plurality of adjusting rotary knobs are further arranged. A wavelength index dial and a light transmittance indicator gauge are arranged on the body, and a hidden box cover used for placing a spectrophotometer is further arranged on the body.

Description

[0001] Technical field [0002] The invention relates to a measuring device, in particular to a spectrophotometer test device. Background technique [0003] A spectrophotometer, also known as a spectrometer, is a scientific instrument that decomposes light with complex components into spectral lines. The measurement range generally includes the visible light region with a wavelength range of 400~760 nm and the ultraviolet region with a wavelength range of 200~400 nm. Different light sources have their own unique emission spectra, so different luminous bodies can be used as the light source of the instrument. Temperature and humidity are important factors that affect the performance of the instrument. They can cause corrosion of mechanical parts, reduce the finish of the metal mirror, cause errors or performance degradation of the mechanical parts of the instrument; cause the aluminum film of optical parts such as gratings, reflectors, focusing mirrors, etc. to rust, resulting in ...

AI Technical Summary

Problems solved by technology

They can cause the corrosion of mechanical parts, reduce the smoothness of the metal mirror, cause errors or performance degradation of the mechanical parts of the instrument; cause the aluminum film of optical components such as gratings, reflectors, and focusing mirrors to corrode, resulting in insufficient light energy, stray light, Noise, etc., even the instrument stops working, thus affecting the life of the instrument
