Multi-channel broadband high-resolution spectrograph

The invention discloses a multi-channel broadband high-resolution spectrograph which comprises a plurality of light source entrance slits, a multi-channel integrated grating composed of a plurality ofsub-gratings, a two-dimensional focusing imaging mirror shared by multiple channels and a two-dimensional area array detector which are sequentially arranged along a light source entrance or reflection path. Incident light enters the corresponding integrated gratings along the light source entrance slits and is focused by the shared two-dimensional focusing imaging mirror after being diffracted by the integrated gratings, and diffraction light in a full spectrum area enters the focal plane of the two-dimensional area array detector for detection. And no mechanical displacement part is used, multi-channel full-spectrum high-speed detection and analysis are realized, and very high spectral resolution and working reliability are achieved. 本发明公开一种多通道宽带高分辨光谱仪，包括沿光源入射或反射路线，依次设置的若干光源入射狭缝、由多个子光栅组成的多通道集成光栅、多通道共用的二维聚焦成像镜，以
