Key Features
- Broadband performance
- Extremely fast switching speeds
- Silent, vibration‐free
- Low‐voltage operation
- OEM sizes and shapes
- No mechanical motion
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.Common Specifications
