Splitter

Abstract

The invention relates to a light splitter, and the light splitter comprises a housing main body which is provided with a non-opaque part; a light-splitting device which is stored in the housing main body; a supporting part which is disposed in the housing main body, located at the bottom of the housing main body and used for supporting the light-splitting device; and a wire pin which is connected with the light-splitting device and used for transmitting an electric signal from the light-splitting device. The light-splitting device comprises a transmitting part which is used for transmitting the light from the non-opaque part, a light-splitting part which is used for the splitting of the light from the transmitting part, an analyzing assembly which is used for analyzing the light from the light-splitting part, and a first conductive sheet which is electrically connected with the analyzing assembly. According to the invention, the arrangement of the housing main body, the light-splitting device, the supporting part and the wire pin effectively reduces the assembly difficulty of the light splitter and improves the working efficiency of assembly. The light-splitting device works stably under the stable supporting of the supporting part and the sealing of the housing main body, thereby improving the stability of the light splitter.

Description

technical field [0001] The present invention relates to the field of optical analysis, in particular to optical splitters. Background technique [0002] Optical splitters are passive devices, they require no external energy, only input light. The beam splitter consists of entrance and exit slits, mirrors and dispersive elements, and its function is to separate the required resonant absorption lines. [0003] In recent years, the development of small spectrometers suitable for various spectrometers and measurement systems has been progressing. In a small spectrometer, it is necessary to arrange each optical element, such as a light incident part, a light detection element, and a spectroscopic part, with high positional accuracy, and to compact the package. This small spectrometer can perform light analysis on the spot no matter where it is used, and can be used for environmental measurement, confirmation of sweetness of fruits, etc., color correction of printers, etc. Ther...
