Paper Abstract

Advances in two dimensional detectors have created a need for a spectrograph that can produce high fidelity images. Aberrations that detract from image quality in conventional spectrographs are discussed. Ray trace and experimental results obtained for a unique spectrograph designed for use with array detectors, i.e., designed to produce high fidelity images, are presented. The spectrograph employs toroidal mirrors to achieve stigmatic imaging in a flat focal field.
