Brewster telescopes are useful for anamorphic image formation or for anamorphic beam compression. With an array of micro-Brewster telescopes a wide uniform beam can be compressed into many beams of a smaller diameter. Thus arrays of microprisms might form an array of micro-Brewster telescopes, which can be used as array illuminator.
