| Abstract: | 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. |
