Abstract

An elliptical lens comprises a lens body having a proximal section and a distal section. The proximal section has at least one input surface for receiving light from a light source and the distal section has at least one output surface through which light exits the lens body. The proximal section further comprises a substantially elliptical peripheral surface receiving at least a portion of the light entering the lens body via the at least one input surface and directing at least some of the received light via total internal reflection to the distal section such that at least a portion of the light directed to the distal section exits the lens body through said at least one output surface. Optical assemblies having said elliptical lens may be embedded in medical devices such as endoscopes to provide efficient illumination.
