Inorganic Waveplate
Nano-ordered microfabrication technique
RICOH Industrial Solutions Inc.'s inorganic waveplate (quarter-wave plate and half-wave plate) has attained a high reliability that conventional waveplates never have.
The waveplate is manufactured by using a nanometer-order micro glass fabrication technique.
Benefits
- High reliability (heat resistance)
- Light resistance
- Thin plate (t=0.3mm ~)
- Chemical resistance
- Environmentally friendly (Halogen-free, RoHS compliance, etc.)
- Superior in incidence angle dependence (very small property changes even at an angle of ±10°)
- Easy to develop complex elements on one substrate (e.g.,(1)waveplate with grating(2)waveplate with polarizer and(3)waveplate with reflecting mirror)
- Easy to design and develop polarization function as desired area at the same surface on a substrate

Cutting Element
Contact us to inquire about even the precision cutting of various components.
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.
