Problems solved by technology

Different types of spectrometers have different requirements for light sources, so the current light source systems used in spectrometers are all instrument-specific, single-function, and not universal
This increases the design and processing costs of spectroscopic instrument products, and also restricts the development of spectroscopic instrument industry

Abstract

The invention relates to a multifunctional reconfigurable light source system which comprises a light source alignment module, a sampling module and a focusing and modulating module, wherein the three discrete modules are connected through connecting bosses and connecting clamping grooves, or the three modules are arbitrarily combined to assemble into light source devices having different applications; the light source alignment module changes light of continuous and fixed-point wavelengths of different wave bands, such as ultraviolet light, visible light or infrared light, and the like into parallel light; the focusing and modulating module focuses the parallel light at a light outlet of the light source; and the sampling module places a transmission sample in a light path to acquire light signals of the sample information. The invention has both generality and specificity, can be assembled into special light sources aiming at light of different bands, such as the ultraviolet light, the visible light or the infrared light, and the like and different types of spectrometers such as light filters, grating spectrometers, and the like by selecting different modules and combines multiple functions into a whole. The light source system not only has the functions of spectrometer light sources, but also can realize the functions of light modulating, light splitting, sampling, and the like of the spectrometers, thus the light source system solves the problem of single application of the traditional spectrometer, reduces the cost and improves the efficiency.

Description

technical field [0001] The invention relates to a light source device, especially a reconfigurable light source device suitable for spectroscopic instruments. Background technique [0002] As a commonly used analytical instrument, spectrometer has a wide range of applications. [0003] The spectroscopic instrument is composed of light source, monochromator, detector, sampler, acquisition and control, power supply and other parts. The light source system is to provide the required band of light for the spectrometer. There are many kinds of spectrometers, which can be divided into ultraviolet, visible, near-infrared, mid-infrared, etc. according to the band; according to the spectroscopic device, it can be divided into four types: optical filter, grating spectroscopic, Fourier transform and acousto-optic tunable. Different types of spectrometers have different requirements for light sources. Therefore, the light source systems used in spectrometers are all instrument-specifi...
