Paper Abstract

The association of a photoresist grating and a prism usually called 'grism' by astronomers is studied in detail from the efficiency point of vue with the Differential Theory of Diffraction Gratings. Starting from the grism equation, the blaze properties of echelette transmission gratings are studied in visible region as functions of blaze angle and groove spacing. The influence of incidence is considered. The asymptotic case of echelle is studied too. A special solution for perfect blazing is given.
