Key Features

  • Phase of Amplitude modulation of UV spectrum
  • Analog modulation
  • Non-mechanical polarization control
  • Low absorption
  • High UV tolerance LC
Liquid crystal technology for polarization control now extends into the ultraviolet. While standard LC materials are susceptible to UV light damage below 450 nm, Meadowlark has designed a new UV-resistant LCVR material capable of operating at lower wavelengths (as low as 350 nm). These parts can be custom-configured for use as variable attenuators or polarization rotators and are compatible with our standard line of liquid crystal controllers.
