Abstract
Methods and systems for correcting chromatic aberrations in a telescope incorporating a diffractive primary optical element are provided. In particular, a corrective optic assembly that includes a corrector diffractive optical element (DOE) is described. The corrective optic assembly provides light to the corrector DOE at a high incidence angle. Moreover, light is reflected from the corrector DOE at a high exit angle comprising a cylindrical Littrow configuration allowing for greater bandwidth and smaller size.
