Prism mounting device

Abstract

The invention discloses a prism mounting device. A chassis is arranged on a base; a bottom end of a locking pin penetrates the chassis from top to bottom and form a thread fit with the base; a limiting member pressing against a top surface of the chassis is arranged on the locking pin; a plurality of longitudinal adjustment devices are arranged between the base and the chassis; a tray is arrangedon the chassis; positioning blocks which are pressed against a prism in the circumference direction are arranged on the tray; a vertical column is arranged on one side of the tray; a pressing plate and a spring plate which are opposite to each other are successively arranged on the top of the vertical column from top to bottom; a free end of the pressing plate and a free end of the spring plate are positioned above the prism; a pressing plate seat is arranged under the spring plate; a steel ball is arranged between the pressing plate seat and the spring plate; a limiting holding structure matching the steel ball is arranged on the top of the pressing plate seat; and a locking nail which forms a thread fit with the pressing plate and is pressed against the spring plate penetrates the pressing plate in the vertical direction. The prism mounting device can accurately and reliably mounts the prism so as to improve the product imaging effect and the data accuracy of the spectrometer.

Description

technical field [0001] The invention relates to the technical field of optical matching components of spectrometers, in particular to a prism installation device. Background technique [0002] In the prior art, prisms are used as spectroscopic elements in some spectroscopic instruments to split light. Therefore, the installation of prisms is particularly important. The installation position of prisms is accurate and stable, which can make the imaging of the instrument clear and of good quality, which is beneficial to spectral analysis. If the installation position of the prism is inaccurate, resulting in poor imaging effect of the instrument, it will cause a large error in the data obtained by spectral analysis, which will seriously affect the accuracy of the analysis results. [0003] In the current existing prism installation technology, the prism is usually directly fixed and installed on the prism chassis, but this assembly and installation structure only plays a role in...

[0002] In the prior art, prisms are used as spectroscopic elements in some spectroscopic instruments to split light. Therefore, the installation of prisms is particularly important. The installation position of prisms is accurate and stable, which can make the imaging of the instrument clear and of good quality, which is beneficial to spectral analysis. If the installation position of the prism is inaccurate and the imaging effect of the instrument is not good, it will cause a large error to the data obtained by spectral analysis, which will seriously affect the accuracy of the analysis results.

[0003] In the current existing prism installation technology, the prism is usually directly fixed and installed on the prism chassis, but this assembly and installation structure only plays a role in fixing the prism, and the accuracy of the installation position of the prism depends entirely on the prism, the prism chassis and the The processing accuracy of some related mechanical parts is guaranteed, which undoubtedly increases the processing difficulty and production cost of prisms and related accessories, and if the processing accuracy of prisms and related accessories cannot be guaranteed, it will directly affect the imaging effect of spectral analysis instruments and data error
