Quartz (SiO2) Crystals
Crystalline quartz is a positive
uniaxial crystal with a moderate birefringence over the broad
transparent range from 200 nm to 2300 nm. The excellent physical,
chemical, and optical properties of crystalline quartz such as high transmittance
in ultraviolet, visible and infrared, the
resistance to moisture, high damage threshold, and resistance to scratch
make it the most favourable material for fabrication of birefringent filter plates,
waveplates
and many other birefringent components.

Quartz components for phase or time delay compensations are highly customized. Please
contact us for quartz components that best suit your applications.
Coatings:
Quartz
windows or blocks are uncoated unless the coating is specified.
Input and output
faces can be
AR coated with R<0.25% at the specified central wavelength. Please specify
the coating and append to the part number, e.g. QAR5010-A-AR800 for the
quartz plate with the AR coating @ 800nm.
Common AR coatings: AR@266, 355, 400, 532, 800, 1064nm, dual
AR@800/400nm, 1064/532nm, and broadband AR@400-700nm (VIS).
Mount:
For customer convenience and protection of crystals, crystals with T≤
3.0mm are mounted in a 1" anodized aluminum holder. Thicker crystals can be mounted in a 1" holder upon request.
