MEMS Optical has the
capability to make high performance gray scale injection molded
plastic optics and molds for injection molding of plastic optics.
High performance plastic optics are
possible due to the use of our patented gray
scale technology. Diffractives (beam
splitters, top hat beam shapers,
holograms) with efficiencies of between 75% to 90% can be achieved.
Plastic refractive microlenses are also possible and they can be
spherical, aspherical, torroidal, square shaped, round shaped, hexagonal,
or cylindrical. This allows the inherent advantages of plastic (high-production
quantities at low cost) ) to be achieved while still achieving performance
far superior to binary optics.

looks rough, it is the actual surface structure required
to produce a square holographic pattern.
