Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] Such as figure 1 As shown, the multi-channel low stray light spectrometer based on the area array detector of the present invention includes two parts: an optical platform 8 and an optical signal acquisition and processing device 9, the incident light beam passes through the incident slit 1 to the inside of the spectrometer, and after passing through the collimating mirror 2 Further incident on the dispersive element 4, the dispersive element 4 splits the light beam, and projects the image of the dispersive spectrum onto the multi-channel area array detector 6 through the optical focusing imaging system 3, and the arrayed band-stop filter window 5 is located at the multiple Before the channel area array detector 6, the structure of the array type band-stop filter window 5 is as follows figure 2 As shown, 5-1 is the reference channel, 5-2 is the measu...
