- First order Quartz Waveplates
- Made from high quality optical grade crystalline quartz
- 17mm by 17mm square clear aperture
- Mounted in a metal ring with engraved wavelength identification
- Optically contacted for precision retardation
- Both quarter wave and half wave retardation versions available
|
These are formed from two thin sections of crystalline quartz which have been
cut to include the optic axis. The two sections are polished to different thicknesses
in order to be have exactly the required retardation difference. They are then
optically contacted with the axes opposed. In this way it is possible to provide
precise first order retardation in a plate of usable thickness. The plates are
17mm square with a combined thickness of 5mm. They are mounted in a 30mm diameter
by 6mm thick cell with the combined optic axis along the diagonal. The cell
is engraved with the wavelength and the retardation. We offer both 
/4
retardation and /2
retardation waveplates for a variety of wavelengths.
