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
  • Wide Angle Acceptance
  • Better Temperature Bandwidth
  • Wide Wavelength Bandwidth
  • AR coating, R<0.2%

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.
