Abstract
An illumination device includes a laser source, a conventional diffuser element, and an extender optic with a curved interior surface and a curved exterior surface. Light emitted by the laser source with a given field of illumination (FOI) is received by the conventional diffuser element and outputted towards the interior surface of the extender optic with an increased FOI; the exterior surface of the extender optic then outputs the light received by the interior surface as light with an even greater FOI, usually in the range of 120°-185°.
