Abstract : An optical prism, with an input surface, a reflecting surface and a base, and with a diffraction grating formed on the reflecting surface. The prism is designed so that if an input beam is incident normal to the input surface, then efficiency of the order diffracted in the direction opposite the input beam is greater than a predetermined value. If the prism is fabricated of a material with index of refraction n, then the resolving power of the grating is increased by n.
