Diffuse reflectors
First Claim
Patent Images
1. A diffuse reflector, comprising:
- a reflecting element; and
a diffusing adhesive adhered to the surface of the reflecting element, the diffusing adhesive altering the directionality of light as it transmits through the diffusing adhesive while preserving an initial polarization state of the light.

Abstract
Highly efficient diffusely reflecting multilayer mirrors diffusely reflect light incident upon them. Highly efficient diffusely reflecting multilayer polarizers diffusely reflect light of one polarization while diffusely transmitting the other polarization. The diffusely reflecting mirror includes a light diffusing element and a multilayer mirror element. The diffusely reflecting polarizer includes a light diffusing element and a multilayer reflective polarizing element.

15. A diffusely reflecting polarizer, comprising:
-
a reflective polarizer, the reflective polarizer reflecting light of a first polarization state and transmitting light of a second polarization state; and a diffusing adhesive adhered to a surface of the reflective polarizer, the diffusing adhesive being adapted to diffuse light transmitted through the diffusing adhesive while substantially maintaining the polarization of the light.

16. A diffuse reflector, comprising:
-
a reflecting element having spectral variations in at least one of reflected and transmitted light; and a polarization preserving diffuser disposed to improve the spectral uniformity of the at least one of reflected and transmitted light. - View Dependent Claims (17, 18)

19. A diffuse polarizing reflector system, comprising:
-
a reflective polarizer that reflects light of a first polarization and transmits light of a second polarization, the reflective polarizer having changes in at least one of spectral reflectivity and transmission; and a polarization preserving diffuser disposed to improve the spectral uniformity of light that is at least one of reflected and transmitted by the reflective polarizer. - View Dependent Claims (20, 21, 22)
