Title:
POLARIZING BEAM SPLITTER PLATES PROVIDING HIGH RESOLUTION IMAGES AND SYSTEMS UTILIZING SUCH POLARIZING BEAM SPLITTER PLATES
Document Type and Number:
Japanese Patent JP2019079062
Kind Code:
A
Abstract:
To increase effective resolution of imaged light reflected from a polarizing beam splitter.SOLUTION: Polarizing beam splitter plates 104 and systems incorporating such beam splitter plates are described. The polarizing beam splitter plate includes a first substrate and a multilayer optical film reflective polarizer 106 that is disposed on the first substrate. The polarizing beam splitter plate includes a first outermost major surface and an opposing second outermost major surface that makes an angle of less than about 20° with the first outermost major surface. The polarizing beam splitter plate is adapted to reflect imaged light 120 received from an imager 102 towards a viewer or screen with the reflected imaged light having an effective pixel resolution of less than 12 μm.SELECTED DRAWING: Figure 1
