AQWP2 - Quarter Waveplates
The AQWP2 is a lower cost alternative than multi layer achromatic retarders. The achromatic quarterwave retarder converts incoming plane polarized light into circular polarization the same as AQWP3 but has a smaller effective bandwidth. The AQWP2 broadband waveplate is popular with micro display manufacturers needing to miniaturize wearable products or for optical isolation in display systems.

Visible Broadband Quarterwave Retarder
A single film broadband quarter waveplate. The AQWP2 retarder does not exhibit the dramatic dispersion seen in single layer retarder films or suffer from high out of plane retardance. The AQWP2 is available as a free standing film, but is only 90 microns thick.
Advantages of broadband retarder
Distinctly useful for OEM applications
Form Factor – Free standing waveplates can be sliced or die cut specifically for custom applications. The AQWP2 retarder can be cut into geometric shapes using a digital cutter.
Cost – Per unit cost contracts due to less raw materials and labor. The retardation characteristics are exactly the same as our standard product. Some designs do not call for low transmitted wavefront or high abrasion resistance. If this is true for you, the free standing polymer achromatic waveplate may be a wise choice to consider.
