Abstract
A power lens for use in an automated color mixing wash luminaire is formed of a disc of cast transparent material. The disc includes a plurality of lens elements in a honeycomb pattern. Each element has a convex surface. The convex surfaces form an arcuate band extending around a surface of the disc. The convex surfaces have various radii. A plurality of lens elements having the same radius are grouped together in abutting relationship. Six different radii are represented in the lens so that six groups of elements are formed around the band.
