Concave Holographic Gratings for Flat-Field Spectrographs
Aberration corrected flat field gratings are designed to focus a spectrum on a plane surface, making them ideal
for use with linear or 2-D array detectors. These gratings are computer-optimized to form near-perfect images of the entrance slit on the detector plane. The relative location of grating
to detector is kept fixed.
