ABSTRACT:
A color changer for use with a wide angle light source which includes a frame, a plurality of planar dichroic filter strips mounted on the frame and aligned substantially parallel to each other. The filter strips have identical predetermined optical filtering characteristics with first and second sets of the filter strips movable along a common axis so as to vary the gap between them and at least alternate ones of the filter strips in each of the first and second sets set at an angle such that, when the color changer is positioned in a beam of light transmitted from the wide angle light source, a substantially constant angle of incidence is maintained with respect to light from the light source incident on the alternate ones of the dichroic filter strips.
