A Spectrograph Based on Efficient Adjustment of Light Incident

Abstract

The invention discloses a spectrograph based on the high-efficiency adjustment of the amount of incident light, which belongs to the field of spectrographs. This solution can realize that during the use of the device, the push handle pushes the slider to squeeze the air in the sleeve, causing The airbag package connected with it expands and moves to the right to cover the gap between the slit edges and prevent dust and dirt from entering the adjustable slit from the gap. When adjusting the light aperture of the adjustable slit , because the airbag is in the process of returning to its original state, the alcohol stored in the airbag is squeezed from the permeated part of the diaphragm, and the adsorption line absorbs the infiltrated alcohol, thereby cleaning the dust on the surface of the slit knife edge, and when the adjustable narrow When the slit adjusts the light input of the light source, the transparent inflatable airbag expands due to the heat irradiated by the light source, and the light source shines on the surface of the convex mirror ball, and the convex mirror ball refracts the light source irradiated on its surface into the light hole adjusted by the adjustable slit , so that the light incident amount of the light source of the adjustable slit is increased.

Description

technical field [0001] The invention relates to the field of spectrographs, and more specifically relates to a spectrograph that can be efficiently adjusted based on the amount of incident light. Background technique [0002] Spectroscopy studies the generation of spectra of various substances and their interactions with substances. Spectrum is the orderly arrangement of electromagnetic radiation according to wavelength. Through the study of spectra, people can obtain the energy level structure of atoms, molecules, and electrons. The knowledge of various material structures such as configuration, chemical bond properties, and reaction kinetics also provides important qualitative and quantitative analysis methods in chemical analysis. Emission spectra can be divided into three different types of spectra: line spectra, Banded spectrum, continuous spectrum, line spectrum is mainly produced by atoms, banded spectrum is mainly produced by molecules, and continuous spectrum is mai...

AI Technical Summary

Problems solved by technology

[0003] At present, during the use of the spectrograph, it may be necessary to check whether there is dust on the slit edge due to the fact that there are many burrs on the collected spectral curve, so as to clean the slit edge and reduce work efficiency. Sharp, close to each other is easy to produce edge curling, which will damage and destroy the edge of the knife, resulting in the intrusion of some dust and debris, which may affect the spectral research
