Spectrum equipment

The invention relates to the field of optics, in particular to spectrum equipment comprising an excitation head, the excitation head is used for emitting sparks, a light ray processing module and a temperature adjusting module are arranged in a containing cavity, and the light ray processing module is used for receiving, processing and recognizing light rays generated when the sparks excite an object to be detected. A semiconductor temperature adjusting piece in the temperature adjusting module is used for providing different adjusting temperatures for the light processing module according to different driving currents, and the driving currents are matched with the environment temperature of the current environment of the excitation gun. Therefore, when the environment temperature exceeds the preset temperature, the temperature in the excitation gun can be accurately adjusted, and it is guaranteed that the stability and safety of the functional module in the light chamber in the excitation gun are good. 本发明涉及
