摘要:
The light transmission of an astronomical spectrograph could be increased if the collimator were eliminated, the aberrations that arise at the diffraction grating in a diverging beam from the slit being corrected in the spectrograph camera. This possibility is explored, and designs given for two such systems suitable for low-dispersion, faint-object spectroscopy.
