Abstract

An optical system having a radiation transparent member and an anti-reflective embossment embossed into at least one surface of the transparent member. The embossment has spaced structures configured to permit incident radiation to pass through the embossment and the radiation transparent member, and to, at least, attenuate reflection of the incident radiation off the embossment. The structures are maximally spaced from one another by a subwavelength of the incident radiation.
