Integrated miniature spectrometer

Abstract

The integrated miniature spectrometer consists of two parts of beam splitting and imaging one and spectral signal acquiring and processing one, the beam splitting and imaging part consists of incident fiber, concave grating, planar reflector, base, upper casing and other elements and devices; while the spectral signal acquiring and processing part consists of photoelectronic detector array, spectral signal read-out circuit, A / D converter circuit, spectral signal processing circuit and analysis software. The present invention integrates incident fiber, concave grating, planar reflector, photoelectronic detector array, etc. and may be used widely in on-line real-time detection and analysis of scientific experiment, biochemical analysis, environment monitoring and other fields.

Description

Technical field [0001] The invention belongs to the technical field of analytical instruments, in particular to an integrated miniature spectrum analyzer. Background technique [0002] In the prior art, corresponding products of micro-spectrometers have come out abroad. There are still some defects and deficiencies in the application. For example, the finger-up spectrometer of Steag Microparts in Germany uses a concave grating as a spectroscopic element. However, due to the small longitudinal section of the grating, the light energy utilization rate is low, it is not convenient for weak light detection, and it is difficult to process. Another example is the handheld fiber optic spectrometer of Ocean Optic Company in the United States. It uses more optical components and has a more complicated structure, and has not fundamentally changed the structure of the traditional spectrometer. In addition, there are still great difficulties in installation and debugging, and the repe...

Problems solved by technology

For example, the finger-up spectrometer of Steag Microparts in Germany uses a concave grating as a spectroscopic element. However, due to the small longitudinal section of the grating, the light energy utilization rate is low, it is not convenient for weak light detection, and the processing is difficult.

Another example is the handheld fiber optic spectrometer of Ocean Optic in the United States, which uses more optical components and a more complex structure, and has not fundamentally changed the structure of traditional spectrometers.

In addition, there are still great difficulties in installation and debugging, and the repeatability is poor

From the open literature, there is no report about the miniature spectrometer in China.
