Abstract

An illumination system for illuminating an object includes a light source and a lens array system. The light source includes an illumination element emitting light rays and surrounded by a parabolic reflector. The lens array system includes a first lens array plate and a second lens array plate. The first lens array plate includes a matrix of lenslets where, in one embodiment, each lenslet has a shape matching the aspect ratio of the object to be illuminated. The second lens array plate includes a radial pattern of wedge shaped lenslets each corresponding to a lenslet in the first lens array plate. 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.
