Abstract

We present a CTIS system that uses an optimized diffractive optical element (DOE) to project the spectral and spatial information simultaneously onto a CCD. We compare the DOE with and older approach based on glass gratings and found that the DOE gave an improved spectral response. We argue that a DOE is the most effective approach for CTIS.
