Abstract
Polarizing beam splitters and systems incorporating such beam splitters are described. More specifically, polarizing beam splitters and systems with such beam splitters that incorporate multilayer optical films and reflect imaged light towards a viewer or viewing screen with high effective resolution are described.
Claims8
A polarizing beam splitter comprising:
- a reflective polarizer disposed between first and second prisms;
- and an optical layer bonding the reflective polarizer to at least one of the first and second prisms, wherein the polarizing beam splitter is configured to reflect an imaged light towards a viewer or a screen, an effective pixel resolution of the imaged light being less than 12 microns after reflection from the polarizing beam splitter.
