QCL laser spectrometer with adjusting function

Abstract

The invention provides a QCL laser spectrometer with an adjusting function. The QCL laser spectrometer comprises a laser device, a laser adjusting assembly located on one side of the laser device and used for adjusting the direction of a laser light path, a laser reflecting assembly located on one side of the laser adjusting assembly, a light beam splitting piece located on the upper portion of the laser reflecting assembly, a detector located on the upper portions of the light beam splitting piece and the laser reflecting assembly, and a first reflecting mirror positioned at the upper part of the light beam splitting piece. According to the QCL laser spectrometer with the adjusting function, when the direction of the laser light path is adjusted, laser emitted by the laser adjusting assembly irradiates the laser device and the laser reflecting assembly respectively, the laser reflecting assembly reflects the laser to the light beam splitting piece, and the light beam splitting piece splits the laser into two beams which are respectively irradiated on the detector and the first reflecting mirror so as to adjust the direction of the laser device irradiating the laser on the laser reflection assembly, so that the adjustment of the light path of the laser device irradiating the laser reflecting assembly is facilitated, and the adjustment efficiency is improved.

Description

technical field [0001] The invention relates to the field of QCL laser spectrometer with adjustment function, in particular to a QCL laser spectrometer with adjustment function. Background technique [0002] With the rapid development of optical technology and lasers, lasers are widely used in welding, cutting, laser cleaning, spectral measurement, spectral analysis, gas monitoring and other fields. The power requirements of lasers are also getting higher and higher, and it is difficult for low-power lasers to meet the requirements. , in the application field of laser spectrometer, the laser emits laser light, and then the laser light is reflected by the reflector, and enters the detector after penetrating the measured substance. The laser spectrometer in the prior art is infrared light, which is difficult to distinguish with the naked eye. Difficult to calibrate, inconvenient to adjust, affecting adjustment efficiency. [0003] Therefore, it is necessary to provide a QCL l...
