Key Features
Meadowlark Optics’ Achromatic Ferroelectric Polarization Rotator features high speed and exceptional polarization purity over broad wavelength ranges. FLC devices offer a significant performance advantage in optical shutter and rotator applications demanding the fastest optical response times available.
Since these devices are solid-state – undesirable mechanical motion, associated noise, and vibration problems are eliminated. Key features of our FLC devices include 100-microsecond switching speed, high contrast linearly polarized output, and operation over the widest wavelength range available.
Typical applications of the FLC Achromatic Rotator include single-camera 3D video capture, broadband phase modulators, beam steering, and polarimetry. Achromatic rotators are not limited to visible spectrum; we can design and build them in the near-infrared as well.Retarder Material: Ferroelectric liquid crystal
