A digital cinema projection apparatus having an illumination source with a
first etendue value for providing polarized polychromatic light. A first
lens element lies in the path of the polarized polychromatic light for
forming a substantially telecentric polarized polychromatic light beam. A
color separator separates the telecentric polarized polychromatic light
beam into at least two telecentric color light beams. At least two
transmissive spatial light modulators modulate the two telecentric color
light beams. There is an etendue value associated with each spatial light
modulator. The etendue value is within 15% or greater than the first
etendue value corresponding to the illumination source. A color combiner
combines the modulated color beams along a common optical axis, forming a
multicolor modulated beam thereby; and a projection lens directs the
multicolor modulated beam toward a display surface.
