Color corrector for embedded prisms

DETAILED DESCRIPTION In carrying out principles of the present invention, in accordance with a preferred embodiment thereof, an embedded prism includes a prism body formed of a first material, and prism means mounted within the body forming an interface with the body and being formed of a second material having an index of refraction substantially equal to the index of refraction of the material of the body at a selected wavelength.
Light entering the prism body is transmitted to an exit area through the prism means, but is subject to color aberration.
Correcting means are coupled with the prism body for correcting the transmitted light beam for the color aberration.
In accordance with one specific embodiment of the invention, the correcting means comprises a correcting wedge mounted in the exit area.
According to another feature of the invention, the correcting wedge is formed of a material having the same index of refraction as the index of refraction of the prism means.
