Abstract
The present invention relates to an apparatus for polarizing an incident light beam. In embodiments, a tile wave plate assembly is provided. The tile wave plate includes a layered structure having a substrate plate and two layers of mosaic tiles. The layers of the apparatus are mechanically separated to form a controlled gap spacing. The mosaic tiles can be configured to form a pseudo or true zero order wave plate.
