Abstract
An optical output device comprises a plate having at least one surface formed as an array of tessellated lenses. The tessellated lenses comprise at least first and second regions of regular hexagonal lens tessellation, wherein the first and second regions are slanted with respect to each other. By removing full periodicity in this way, but maintaining localized periodicity, visible non-uniformities are reduced in both color and intensity. The optical output device does not need to be illuminated uniformly to generate an output without visible intensity or color edges.
