ABSTRACT:
A digital projection display includes a light source producing a light beam, and an integrator, an illumination lens, an illumination fold mirror, a light director, and a digital light modulator which sequentially process the light beam. The digital projection display further has a projection lens that receives the spatially modulated light beam from the light director and includes two projection lens elements. A projection lens fold mirror is disposed between the two projection lens elements. A projection fold mirror receives the light beam from the projection lens and redirects the light beam to a display.
