Abstract
A baffle containing a plurality of small apertures is mounted on the receiver aperture of an optical receiver, such as a wireless optical telecommunication system receiver. The baffle attenuates ambient radiation that may interfere with the optical receiver. The baffle includes a plurality of apertures that have their axes substantially parallel to the optical axis of the receiver.
