Abstract
A planar parallel plate direct vision prism including two glasses for dispersing light as a function of color is disclosed. Also disclosed is an optical system which includes a first optical assembly having two planar parallel plate direct vision prisms for dispersing light as a function of color. The degree and orientation of the light dispersed is controlled by rotating the two prisms of the first assembly in relation to each other and together in unison. A fiber optic bundle transmits the dispersed light and a second optical assembly having two planar parallel plate direct vision prisms recombines the dispersed light emerging from the fiber optic bundle. The degree and orientation of the light recombined is controlled by rotating the prisms of the second optical assembly in relation to each other and together in unison.
