Abstract
A dielectric mirror including a substrate and a reflector portion disposed directly on the substrate. The reflector portion includes alternating layers, e.g. in excess of 150 alternating layers, of high and low index of refraction material. In one embodiment, the layers are configured for reflecting each wavelength in a bandwidth of 400 nm at greater than 97.5% reflectivity. In another embodiment, the layers are configured for reflecting an s-polarization and p-polarization of each wavelength in the range from 350 nm to 100 nm at greater than 98% reflectivity. High reflectivity is achieved for a wide range of angle of incidence.
