Optical transmissive component with anti-reflection gratings
First Claim
1. An optical transmissive component having an entrance surface and an exit surface for optical radiation, in which one of the surfaces is provided with an anti-reflection grating, characterized in that a second surface is provided with a second anti-reflection grating and in that the grating strips of the first grating extend essentially perpendicularly to those of the second grating in corresponding areas of the first and the second surface.

Abstract
An optical transmissive component (1) is described, which component has an entrance surface (4) and an exit surface (5) for optical radiation (20), in which one of the surfaces (4; 5) is provided with an anti-reflection grating (10; 15). By providing a second surface, (5; 4) with a second anti-reflection grating and by ensuring that the grating strips (11) of the first grating (10) extend essentially perpendicularly to those (16) of the second grating (15) in corresponding areas of the first and the second surface (4; 5), it is prevented that the component is birefringent.
