Abstract
An optical element including an anti-reflective coating is provided. The optical element includes a silicon substrate and a reflective layer disposed onto a first portion of the surface of the silicon substrate. An anti-reflective layer is disposed onto a second portion of the surface of the silicon substrate such that destructive interference at the anti-reflective layer substantially reduces any reflection of radiation incident on the anti-reflective layer.
