ABSTRACT:
A conical stage lens consisting of three component lenses which receive a concentrated incipient beam of white light and emit a concentrated beam of monochromatic light. A concentrated beam of white light from a conical beam concentrator is received by the upper component lens, refracted through the middle component lens to the lower component lens which separates the beam into the spectral colors. Any one of the spectral colors can be emitted from the lower component lens, which is interchangeable, as a concentrated monochromatic beam, with the other colors being intercepted by a heat-absorbing metal shield and rod.
