Abstract
A double-channel miniaturized Raman spectrometer includes a sequentially-connected near-infrared laser diode or near-ultraviolet laser emitter, a collimated laser beam expander, a first beam splitter that retards laser light but penetrates laser light and Raman light, a cylindrical or spherical objective lens with or without zooming, a second beam splitter that retards laser light but penetrates Raman light, a relay optical system, a slit, two spectral lens, a plurality of line-array or matrix-array CCD or CMOS detectors, a GPS, and a data processing and wireless transceiver system. After the laser channel photographing a target and aligning an optical axis and a Raman channel to measure the sample, the data is wirelessly sent to a cell phone and a cloud computer for spectrum separation, peak search, spectral library establishment, material identification and the like in order to obtain a quick conclusion.
