An optical projection system having optical components immersed in a liquid. An enclosure holds the liquid, a spherical lens, a polarizer, a polarizing beam splitter, a reflective light valve having a retarder foil, and an exit window. The liquid stabilizes the thermal environment, reduces the need for antireflective coatings, enables a reduction in the number of optical components, and enables high optical flux.
