Abstract

The invention discloses a Raman spectrometer of an array structure. The spectrometer comprises a narrow-linewidth LD array, a detection board, a CCD reception array, narrow-linewidth output fibers andsignal reception fibers, the narrow-linewidth LD array is connected with one end of each narrow-linewidth output fiber fiber probes are distributed on the detection board at interval, the other end of each narrow-linewidth output fiber is connected with one fiber probe correspondingly, each fiber probe is connected with one end of one signal reception fiber, and the other ends of the signal reception fibers are tightly arranged into a line and then connected to the CCD reception array. The number of pumping points of a Raman spectrum is increased much, so that the total light intensity of theRaman spectrum is improved by one or multiple magnitude order, and a sample is not burned when a light source is separated, namely, the single-point light intensity still equals the normal light intensity.

Description

technical field

[0001] The invention relates to the field of optical instruments, in particular to an array structure Raman spectrometer. Background technique

[0002] The whole concept of the current Jieman spectrometer is a single light source and a single detection point. Sometimes the light intensity of the light source is too strong, causing the sample to burn. Contents of the invention

[0003] The purpose of the present invention is to overcome the deficiencies of the prior art and provide an array structure Raman spectrometer.

[0004] The technical scheme adopted in the present invention is:

[0005] An array structure Raman spectrometer, which includes a narrow linewidth LD array, a detection plate, a CCD receiving array, a plurality of narrow linewidth output optical fibers and a plurality of signal receiving optical fibers, the narrow linewidth LD array is respectively connected to a plurality of narrow linewidth output One end of the optical fiber is connec...
