Spectral light source system for uniform surface-emitting gas absorption cell

Abstract

The invention discloses a spectrum light source system of a uniform surface luminescence type gas cuvette. The system comprises housings, diffusion coating layers, lamps, lamp radiators, water cooling pipes, a light outlet and a glass cavity body. The diffusion coating layers are arranged on the inner surfaces of the housings. The housings and the diffusion coating layers are connected with the light outlet. The diffusion coating layers are connected with the glass cavity body. The water cooling pipes are installed on the housings. The lamp radiators are installed on the housings. The lamps are connected with the lamp radiators. According to the invention, energy of light at the outlet can be increased; cost is reduced; size is reduced; and gas is saved.

Description

technical field

[0001] The invention relates to a spectral light source system, in particular to a spectral light source system of a uniform surface-emitting gas absorption cell. Background technique

[0002] The gas absorption cell can provide a radiation source with target gas absorption characteristics for the main greenhouse gas detectors in the atmosphere, simulate the spectral radiation characteristics of the atmosphere observed in orbit, and can be used for instrument spectral calibration to achieve spectral resolution and instrument line in the full spectrum. The detection and verification of the type function, and the precise control of the gas concentration and temperature provide basic data for the analysis of the detection capability of the instrument and the inversion of the target gas concentration. The existing gas absorption cells are usually based on the improvement of the traditional White (White) cell and Herriott (Heriott) cell, mainly through the reflect...
