Abstract
An optical sub-system has an optical element having a curved surface featured with a plurality of recurring surface tooling marks. The depth of any surface tooling mark is less than 0.2 wavelengths, whereby light is diffracted on the curved surface. A spatial filter blocks the diffracted light and passes the undiffracted light.
