Abstract
An IR illuminator provides infrared radiation for a digital camera that includes a camera lens including a camera field of view; also including equidistant mounting substrates arranged adjacent to the digital camera with IR LEDs mounted to each mounting substrates and a cover lens positioned over the IR LEDs. The free-form cover lens shape facilitates an emitted radiation emission pattern but prevents visible light reflectivity into the camera lens such that the IR radiation emission pattern has an asymmetric field of view. Two IR illuminators near the camera are angled away from the camera optical direction. The cover lens may be a Fresnel lens, may include a diffractive layer or a collimator to shift radiation emitted from the LED towards an asymmetric distribution.
