Patent ID: 6877882

Claim:
An illumination system for illuminating an object, comprising: a light source including an illumination element emitting light rays and surrounded by a parabolic reflector for directing the light rays; a lens array system for collecting and focusing incident light rays from the light source, the lens array system comprising: a first lens array plate comprising a plurality of lenslets arranged in a matrix configuration; and a second lens array plate comprising a plurality of wedge shaped lenslets arranged in a radial pattern, each wedge shaped lenslet corresponding to a lenslet in the first lens array plate, the second lens array plate superimposing images of the first lens array plate on the object to be illuminated, wherein each wedge shaped lenslet in the second lens array plate has dimensions that are selected to provide a radial and theta collection angles matching the maximum divergence angle of the light source and the maximum divergence angles of the corresponding lenslet in the first lens array plate.
