Abstract

The multiple reflection optical system includes opposing reflecting members of which one is adjoined by entrance and exit slits and is made up of two identical mirrors defining a group arranged symmetrically with respect to one of the slits. The other reflecting member is made up of two concave mirrors of different dimensions. The spacing between the gp. of the identical mirrors and the concave mirrors, as well as the focal length of the concave mirror of the smaller dimensions are 1.5 times the focal length of the concave mirror of the greater dimensions.
