Problems solved by technology

[0003] In the research of patent application or published literature, there is no stable working spectrometer with high resolution and low dispersion under high and low temperature environment and vehicle-mounted vibration conditions. Most spectrometers can only work on a stable optical platform, and the working temperature is generally controlled within the room temperature range. , some high resolutions even require a pneumatic vibration isolation platform and a constant temperature environment to ensure the stability of the spectrometer

Abstract

The invention discloses a high-resolution and low-dispersion grating spectrometer in a solar blind area, which comprises a small aperture diaphragm, a concave reflector, a plane grating and the like. After the sun-blind zone detection signal passes through the aperture diaphragm, it is collimated and expanded, and the position and angle of the plane diffraction grating and focusing mirror are controlled and adjusted to achieve high-precision extraction of the sun-blind zone band optical signal. The invention is not only simple in structure, but also easy to adjust. It can work stably with high resolution and low dispersion in the high and low temperature environment from -30°C to 70°C, on-board and on-board, etc. High-efficiency and high-resolution detection requirements.

Description

Technical field [0001] The present invention relates to the technical field of spectrometers, and more particularly to a high-resolution low-torizens grating spectrometer in a Japanese blind area, in the range of a rocky region, high and low temperature environment and vehicle airborne vibration conditions, low-dispersion high resolution stable operation. Background technique [0002] When sun ultraviolet radiation is passed through the atmospheric layer, the ozone layer in the atmosphere has a strong absorption of 200 nm ~ 300 nm ultraviolet radiation. This wave of ultraviolet radiation is hardly present in the nearland atmosphere, and since the solar radiation of the wave section is in the air layer, especially The atmosphere is basically zero or weak in the atmosphere near sea level, so the band is not affected by the sun radiation, forming a so-called rustic region. There is almost no sun background radiation in the nitestin area, and the atmosphere is almost zero, providing ...
