Patent abstract
An optical system includes a reflection-angle-selective mirror having a substrate, and a reflection-angle-selective coating structure deposited on the substrate. The reflection-angle-selective coating structure has a higher reflectance for light that is incident upon the reflection-angle-selective coating structure at a first incidence angle within an acceptance-angle deviation from a design incidence angle than for light that is incident upon the reflection-angle-selective coating structure at a second incidence angle greater than the acceptance-angle deviation from the design incidence angle. The optical system may also include a light source.
