True Zero Order Waveplates 1/2,1/4

The true zero order waveplate is designed to highly accurate application. Its thickness is very thin(less than 0.1mm) which make the true zero order waveplate excellent in temperature,wavelength and incident angle bandwidth.

To suit different applications,our true zero order wave plates are classified into Cemented true zero order waveplate by Epoxy,Single plate true zero order waveplates,Telecom true zero order waveplate.

Single Plate True Zero Order Waveplates
In order to enable the waveplates suitible for high damage threshold(more than 1GW/cm2) appplication,ULTI Crystal provides a single plate of true zero order waveplate. Considering to the thickness of this waveplate is very thin so that it be very difficult to handle for assembled,so we are stongly recommend to use mounted single plate true zero order waveplates.

Telecom True Zero Order Waveplates for 1310nm and 1550nm
To suit telecom special applications,we are designed and support Telecom series of true zero order waveplates. The primary wavelength is 1550nm although other wavelengths are available. The benefits are accuracy with very short optical path length, excellent temperature stability and extended bandwidths. Each surface of the Waveplate is coated with an anti-reflection coating to maximize the transmission at the specified wavelength.

We offer 1/2 wave,1/4 wave,3/4 wave and 7/8 wave true zero order Waveplates at several telecom wavelengths, and the ¾ wave can be used as a quarter Waveplate with a sign reversal.

ULTI Crystal has a stock position of a wide variety of telecom True Zero Order Waveplates in the telecom band, from 1500nm to 1600nm.
