Inorganic Waveplate

Nano-ordered microfabrication technique

Ricoh Optical's waveplates are made by nano-ordered glass fabrication technique. This is the reason why our products have attained a high reliability, which conventional products would not able to do.


・High durability (heat resistance)
・Light resistance
・Thin plate (t=0.5mm~)
・Chemical resistance
・Environmentally friendly (Halogen-free, RoHS compliance, etc.)
・Easy to develop complex elements on one substrate: waveplate with grating, waveplate with polarizer, waveplate with mirror, etc
・Easy to design and develop retardation function as desired area on a surface of a substrate

Cutting Element

We are available for consultation about various kinds of precision cutting processing of elements.
As for the criteria for cutting precision, please see below.

●High precision cutting of glass substrate
  Cutting precision within ±5μm
  Processing size >□0.5mm
  Thickness 2mm or less
●Standard precision cutting of glass substrate
  Cutting precision ±50μm
  Processing size 12 inch
  Thickness 2mm or less

This makes it possible to produce an area division element.
