The invention includes a color projection system comprising having a light source
optically coupled to a light management device. The light management device being
optically coupled to a polarizer. The color projection system also includes a projection
lens optically coupled to the polarizer. Additionally, a plate is disposed between
the polarizer and the projection lens. The plate has quarter-wave properties. The
light management device has a number of polarizing beamsplitter (PBS) cubes, with
one or more subsets of which are optically coupled to each other, and at least
one light blocking region disposed between a first and a second PBS cube of the
number of PBS cubes. As result reduction of stray light in a reflective projection
system is facilitated.
