Embodiment Construction

[0022] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0023] figure 1 It is a schematic diagram of the first structure adopted by the projection spectrometer system of the present invention. Such as figure 1 As shown, a projection spectrometer system includes a light source module 101, a collimator 102, a beam expander collimating lens group module 105, a reflective grating 103 and a focusing magnifying lens group 104, which are sequentially arranged in the optical path, and may also include a The projection screen or wall or panel 106 is arranged at the front end of the focusing and magnifying lens group 104 in the spectrometer module.

[0024] The light beams emitted from the light source module 101, with wavelengths of λ1, λ2, ..., λn, after being focused and collimated by the collimator 102 and the beam expander and collimator lens group module 105, are incident on the reflective grating 103...

Abstract

The invention discloses a projection spectrometer system, which comprises a light source module, a slit or a collimator, a beam expanding collimating lens module, a grating and a focusing amplifying lens group sequentially arranged in a light path, and a projection screen arranged at the front end of the focusing amplifying lens group. After a light beam outputted from the light source module is collimated and expanded through the slit or the collimator and the beam expanding collimating lens module, through diffraction and light splitting by the grating, spectral image formation and focusing amplifying are then realized through the focusing amplifying lens group, and finally, the light beam is projected to a blank place such as the screen or a wall body or a plate surface. Projection display and spectral analysis are combined, the spectral image generated by the spectrometer is projected to the wall surface of a large solid body such as a classroom, a lab and an office, display change from a small image to a large image is realized, and high-resolution demonstration of the spectrometer in aspects of teaching, experiment and office and the like is facilitated.

Description

technical field [0001] The invention relates to the technical field of spectrometers, in particular to a projection spectrometer system. Background technique [0002] The spectrometer is an analytical measuring instrument widely used in industry and scientific research. It is widely used in environmental monitoring, industrial control, chemical analysis, food quality testing, material analysis, clinical testing, aerospace remote sensing and scientific education and other fields. [0003] At present, the main companies producing spectrometers abroad are: Thermo Scientific, Ocean Optics, B&WTEK in the United States, Jobin Yvon in France, Kaiser Optical System, Companies such as Reni Shaw in the UK and Avantes in the Netherlands, while in China there are mainly companies such as Shanghai Fuxiang, Hangzhou Jingfei, and Hangzhou Yuanfang. The spectrometers of the above-mentioned companies are all at the top level in the industry in terms of performance, but they are mainly aimed...
