Products features:
Zero order waveplate (optically contacted):
Optically contacted
AR coated: R<0.2%
High-damage threshold
Better temperature bandwidth
Wide wavelength bandwidth
Zero order waveplate (air-spaced):
Double retardation plates
AR coated: R<0.2% and mounted
High-damage threshold
Better temperature bandwidth
Wide wavelength bandwidth
True zero order waveplate (cemented):
This type of zero order waveplate is composed of a true zero order waveplate and
a BK7 substrate. As the waveplate is very thin and easy to be damaged, the Bk7 plate's
function is to strengthen the waveplate
Cemented by epoxy
Wide angle acceptance
Better temperature bandwidth
Wide wavelength bandwidth
Zero order waveplate (cemented by epoxy):
This type of zero order waveplate is composed of two multiple order waveplates with
axes crossed. Thus, the effect of the first plate is canceled by the second,
except for the residual difference between these two waveplates
Cemented by epoxy
Better temperature bandwidth
Wide wavelength bandwidth
True zero order waveplate (single plate):
This type of zero order waveplate is designed for high-damage threshold (more than
1GW/cm
2). As the plate is very thin, it's easy to break during operation
Single plate:
Wide angle acceptance
Better temperature bandwidth
Wide wavelength bandwidth
High-damage threshold
Thin thickness: 0.04-0.09 microns
