A brief introduction: The Spider2000 portable two-dimensional Raman imaging spectrometer adopts the research grade micro confocal Raman spectrometer RMS2000 independently developed by Hai Optoelectronics as the Raman core, which enables it to have high sensitivity, high resolution, strong penetration ability, and good ability to suppress fluorescence interference. The optimized optical path design can enable the Raman laser beam to achieve a minimum spot size of micrometer level after passing through the telephoto microscope objective, which can accurately collect Raman spectra of micrometer level samples. In addition, the instrument adopts a high-precision two-dimensional automated mobile platform, which can achieve automatic scanning and mapping imaging functions.
