ABSTRACT:
A Dyson lens system includes a radiation source, a concave mirror, and a plano-convex lens. There is also incorporated in the system an additional lens that is spaced from the plano-convex lens a large part of the distance from the plano-convex lens to the mirror. A roof prism and a turning prism are provided to conduct radiation from the radiation source to the plano-convex lens and also from the plano-convex lens to an image plane. An image adjustor or compensator is provided between the prisms and either the image plane or an object plane--the latter being disposed between the radiation source and the prisms. An adjustment mechanism is provided to effect highly accurate adjustment of the location of the image, the adjustment mechanism including physical shifting to a slight degree of a portion of one or both prisms.
