An embodiment of the utility model provides a raman spectrum detection equipment. This raman spectrum detection equipment includes: the laser instrument for the transmission exciting light, optical devices, be used for with the exciting light guides to need checking sample and collects certainly need checking sample's light signal, the spectrum appearance for carry out the raman spectroscopy of beam split in order to generate need checking sample to the light signal of receiving, and safety detector, be used for detecting the infrared light that need checking sample sent. With the aid of the raman spectrum detection equipment according to above -mentioned embodiment, can prevent to lead to the security problem at the raman spectrum detection in -process because of the overheated damage of sample.
