The invention discloses a microscopic
confocal Raman
spectrometer, comprising a microscopic
confocal Raman module and a single-
grating spectrometer which is matched with the microscopic
confocal Raman module, wherein the microscopic confocal Raman module comprises a reflecting mirror, an angle-adjustable
optical filter bracket, a sample monitoring
optical path, a Raman
optical filter, a microscopic objective lens, a collecting lens and a size-adjustable pinhole.
Laser is focused to a sample by using the microscopic confocal Raman module, so that the sample and the corresponding
laser spots are observed microscopically, and a Raman
signal is microscopically confocal to the size-adjustable pinhole simultaneously, therefore the Raman
signal is detected by using the single-
grating spectrometer. The invention provides a novel microscopic confocal Raman spectrometer with the characteristics of simpleness, economy and convenience for adjustment, so that the
microscopic observation of the sample and the corresponding
laser spots can be achieved, besides, the microscopic confocal Raman spectrometer plays a potential role on Raman spectrum measurement of materials.
