Patent ID: 7712931

Claim:
An illuminator comprising: a light source having an area of light emission and an optical axis extending from said area of light emission, said light source radiating light in a substantially symmetrical pattern surrounding said optical axis on a first side of a first plane, said first plane passing through said area of light emission and perpendicular to said optical axis; an optical element positioned to intercept said radiation pattern, said optical element bisected by a second plane including said optical axis and perpendicular to said first plane, said optical element substantially defined by a light entry surface, a reflecting surface and a light emission surface, each of said surfaces being a surface constructed about and centered on a second axis passing through said area of light emission and located in said first plane, said light entry surface, reflecting surface and light emission surface configured to produce a radiation pattern from said emission surface that is collimated with respect to said second plane and divergent with respect to said optical axis.
