Abstract
An optical diffuser includes a body formed of a material that is at least translucent to light, a back surface for receiving output light from a light source and for scattering the output light received on the back surface to provide diffuse light, and a front surface, on the body opposite the back surface on the body, for transmitting the output light scattered by the back surface as diffuse light with a predefined light distribution.
