Abstract

The invention provides a high-precision multi-dimensional spectrometer detector adjusting structure. The high-precision multi-dimensional spectrometer detector adjusting structure comprises a shell, afocusing and reflecting device, a reflecting device, a light detecting device, an optical grating and an adjustable fixing mechanism, wherein the shell is provided with a slit, the focusing and reflecting device, the reflecting device, the light detecting device and the optical grating are clockwise arranged in the shell, the slit is located between the optical grating and the focusing and reflecting device, the slit faces the reflecting device, the slit, the reflecting device, the optical grating, the focusing and reflecting device and the light detecting device form a spectral path, light can be incident into the light detecting device through the reflection of the slit, reflecting device, optical grating and focusing and reflecting device in sequence, the adjustable fixing mechanism comprises a main fixing block and an angle adjusting device, the main fixing block is provided with a fixing side face and a mounting side face, the fixing side face of the main fixing block is arrangedon the shell through the angle adjusting device, and the light detecting device is arranged on the mounting side face of the main fixing block. The high-precision multi-dimensional spectrometer detector adjusting structure has the advantages that the structure is simple, and the adjustment is convenient.

Description

technical field [0001] The invention relates to a high-precision adjustment structure of a miniature spectrometer detector. The mechanism is used to carry out multi-dimensional precise adjustment to realize the precise coupling between the detector and the optical path. Background technique [0002] As an instrument for measuring light intensity in visible light, near-infrared, ultraviolet and other bands, spectrometer has a wide range of applications, and plays a key role in industrial control, food safety, jewelry inspection, public security and other fields. The miniature spectrometer has the advantages of small size, fast acquisition speed, and good overall modularity. [0003] Most of the miniature spectrometers currently on the market are mainly composed of slits, collimating mirrors, focusing mirrors, gratings, and detectors. During the working process, light is illuminated from the slit to the collimating mirror, the collimating mirror is reflected to the grating, an...
