Modules or Types:

True Zero Order Waveplate-Single Plate
This type of zero order waveplate is designed for high damage threshold application (more than 1GW/cm²). As the plate is very thin, it's easy to break during operation.

Wide Angle Acceptance
Better Temperature Bandwidth
Wide Wavelength Bandwidth
High Damage Threshold
AR Coated, R<0.2%
Single Plate

Standard Wavelength:

λ/2：1310nm, 1480nm, 1550nm
λ/4：980nm, 1064nm，1310nm, 1480nm, 1550nm

True Zero Order Waveplate-Cemented
This type of zero order waveplate is constructed 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.

Standard Thickness:1.1±0.2mm
Cemented by Epoxy

The thickness the this type of the true zero-order waveplates or retarders are very thin, the substrates are added to strengthen the waveplates, but in some applications of high damage threshold (>1GW/cm²), the substrates are not allowed, the special carefulness should be taken in operation on such waveplates without substrates.
Hangzhou Shalom EO offer the two types of true zero order waveplates: the single plate without substrates and the cemented waveplate with substrates. The stocked modules are available for customer's selection in fast delivery and low cost.
