Patent abstract
A compact, high-brightness, integrated illuminator in which collection of light from a point-arc source is maximized by a multi-curvature reflector section configuration of elliptical reflector and segmented spherical retroreflector directing all light rays into a well-defined numerical aperture. The invention also integrates a homogenizer and other optical elements with the multi-curvature reflector section, constructs any or all of these components in a single block of optical material, or, alternatively, constructs these components with molded hollow reflective cavities fabricated in metal or plastic blocks. Cooling is provided by internal fluid channels within the block.
