Abstract

The invention discloses a spectrum module, comprising a seat, a slit structure, a grating structure, a DMD digital micromirror structure and a photoelectric converter. The slit structure, the gratingstructure, the DMD digital micromirror structure and the photoelectric converter are respectively fixed on the seat. The incident light enters the spectrum module through the slit structure. The lightof different wavelengths is separated and sequentially refracted to the DMD digital micromirror structure after splitting by the grating structure. The DMD digital micromirror structure drives different lenses to reflect the light of the corresponding wavelength to the photoelectric converter. The photoelectric converter detects the content of light of different wavelengths in the incident light.Through above design, the entire spectrum module is simple in structure, and convenient in assembly, maintenance and disassembly.

Description

technical field [0001] The invention relates to optical instruments, in particular to a spectrum module and a spectrometer. Background technique [0002] A spectrometer is a scientific instrument that decomposes complex light into spectral lines. It is composed of a prism or a diffraction grating. The spectrometer can measure the light reflected by the surface of an object. The seven-color light in sunlight is the part that can be separated by the naked eye (visible light), but if the sunlight is decomposed by a spectrometer and arranged according to wavelength, visible light only occupies a small range of the spectrum, and the rest are spectra that cannot be distinguished by the naked eye, such as infrared rays and microwaves. , UV rays, X-rays, etc. Through the capture of light information by the spectrometer, the development of photographic negatives, or the display and analysis of computerized automatic display numerical instruments, it is possible to determine what ele...
