Abstract
A prism for color dispersion and recombination and a projector incorporating the prism. The prism comprises an aperture for a light beam and the normal to the aperture defines an optic axis. A first surface, intersecting the optic axis, is oriented at a first angle to the optic axis. The first angle is greater than 45.degree.. The first surface disperses the light beam into a first component and an intermediate component. A second surface, intersecting the optic axis, is oriented at a second angle to the optic axis. The second surface disperses the intermediate component of the light beam into a second component and a third component.
