Abstract
The general expression of the optical path function and the focusing conditions of a variable line-spacing concave grating with a spherical surface are given. The spectral imaging of our flat-field grating spectrograph with a HITACHI flat-field grating was investigated and the typical experimental results of the two modes of the spectrograph (that is, the astigmatic mode and the stigmatic mode) are presented.
