Abstract
A polarizing beam splitter includes a multilayer polarizing film, a first cross-linked silicone gel layer disposed on the multilayer polarizing film, a first rigid cover disposed on the cross-linked silicone gel layer, and a second rigid cover disposed adjacent to the multilayer polarizing film.
Claims25
A polarizing beam splitter, comprising:
- a multilayer polarizing film;
- a first cross-linked silicone gel layer disposed on the multilayer polarizing film;
- a first rigid cover disposed on the cross-linked silicone gel layer;
- and
- a second rigid cover disposed adjacent to the multilayer polarizing film.
2 more elements
A projection system, comprising:
- a light source to generate light;
- an imaging core to impose an image on generated light from the light source to form image light, wherein the imaging core comprises at least one polarizing beam splitter and at least one imager, wherein the polarizing beam splitter comprises:
- a multilayer reflective polarizing film;
- a first cross-linked silicone gel layer disposed on the multilayer reflective polarizing film and between the light source and the multilayer reflective polarizing film;
- a first rigid cover disposed on the first cross-linked silicone gel layer;
- a second rigid cover disposed adjacent to the multilayer reflective polarizing film;
- and
- a projection lens system to project the image light from the imaging core.
5 more elements
A method of making a polarizing beam splitter, the method comprising:
- disposing a multilayer reflective polarizing film between a first rigid cover and a second rigid cover, wherein a first cross-linked silicone gel layer is between the multilayer reflective polarizing film and the first cover and a second cross-linked silicone gel layer is between the multilayer reflective polarizing film and the second cover.
