Abstract
The present invention discloses a coma-elimination broadband high-resolution spectrograph, comprising incident slits, a collimating mirror, an integrated grating, a two-dimensional focus imaging mirror and a two-dimensional area array detector, wherein the incident slits enters along the incident slits, passes through a light through hole in the center of the integrated grating and is incident to the collimating mirror, the incident light enters the integrated grating along a coaxial optical path Lafter collimation of the collimating mirror and is focused by the two-dimensional focus imaging mirror after diffraction of each sub-grating, diffraction light in full spectrum region enters a focal plane of the two-dimensional area array detector for detection along an coaxial optical path L, and off-axis angles of the Land the Lare zero.
