Low-order Waveplate & Multi-order Waveplate

A low-order waveplate is multi-order waveplate with reduced thickness. This type of waveplate is not as thin as a true zero-order waveplate, making it easier to handle, yet it is not as thick as typical multi-order. Use quartz as birefringent material, its thickness is typically designed within the range of 0.1 to 0.3mm. The low-order waveplate exhibits lower temperature sensitivity, a broader bandwidth, and a larger field angle compared to other multi-order waveplates.

The classical multi-order waveplates available in the market generally have a thickness of approximately 0.5 to 1 mm. These waveplates possess relatively low angle acceptance and wavelength bandwidth, and exhibit high temperature sensitivity. Optocity produces lower-order waveplates to decrease temperature sensitivity and increase angle acceptance and wavelength bandwidth at the designated wavelength. The performance of these low-order waveplates is comparable to that of true zero-order waveplates, while being more cost-effective.

Low-order waveplates are increasingly being utilized for both high-power and low-power laser applications. Half waveplates rotate the direction of polarization and quarter waveplates convert linear polarization into circular polarization or vice versa.
