Imaging Characteristics of the Flat-field Grating
The general expression of the optical path function and whole aberration of the variable line spacing concave grating is given. The spectral image of our flat-field grating spectrometer, which employs the HITACHI flat-field grating,is investigated.The typical experimental results of the two operation modes of the spectrometer (i.e. the astigmatic mode and stigmatic mode) are displayed.
