Eigenstate Calibration Set

Meadowlark Optics’ Liquid Crystal Polarization Gratings use varying birefringence to create highly efficient polarization-sensitive gratings. They efficiently diffract circularly polarized light into either the first positive or negative order, depending on the incident light’s handedness. By stacking these gratings and using half-waveplate switches, it’s possible to steer light into 2N discrete angles in 1-D or 2-D arrays.

Also known as geometric phase gratings, Pancharatnam-Berry phase gratings, and diffractive waveplates, these gratings can be customized by Meadowlark. They offer wide-angle beam steering (> 100°), large apertures (> 20 cm), sub-millisecond switching times, reduced size, weight, and power (SWaP) requirements, random-access, inertia-less beam steering, and dynamic focusing.
