Abstract: The present invention discloses a multichannel broadband high-resolution spectrograph, comprising a plurality of light source incident slits, a multichannel integrated grating, a multichannel shared two-dimensional focus imaging mirror and a two-dimensional area array detector which are sequentially disposed along a light source incident or reflection line, wherein the multichannel integrated grating consists of a plurality of sub-gratings, incident light enters the corresponding integrated gratings along the light source incident slits and then is focused by the shared two-dimensional focus imaging mirror after diffraction of the integrated grating, and diffraction light in a full-spectrum region is incident onto a focal plane of the two-dimensional area array detector for detection. No any mechanical displacement part is disposed, multichannel, full-spectrum and high-speed detection and analysis is achieved, and the present disclosure has high spectrum resolution and working reliability.

Abstract: The present disclosure discloses a grating spectrometer having a V-shaped projection light path and capable of eliminating coma aberration. The grating spectrometer includes an entrance slit S1, a grating G, an entrance spherical reflector M1, a focusing spherical reflector M2, and an exit slit S2 which are arranged on a light path in sequence in a light transmission direction. The entrance slit S1 and the exit slit S2 are respectively arranged on two sides of the grating G, and a coaxial entrance light path formed by the entrance slit S1 and the entrance spherical reflector M1 and a coaxial diffraction light path formed by the grating G and the focusing spherical reflector M2 form a V-shaped structure by projection in a diffraction plane. The grating spectrometer has actual population and application value.
