1-inch Quick Liquid Crystal Variable Retarder, Full-Wave, Uncompensated
The LBTEK 1-inch Full-Wave Quick Liquid Crystal Variable Retarder is coated with corresponding anti-reflection coatings for the operating wavelength ranges of 400-700 nm, 700-1100 nm, or 1100-1700 nm. Under the control of an external AC voltage (DC voltage not allowed), it can achieve flexible adjustment of retardation between approximately 100 nm and λ.
With a clear aperture of Ø10 mm, it is mounted in a mechanical housing with attatched wiring. The housing is compatible with Ø1-inch optical component mounts, and the fast axis direction of the liquid crystal variable retarder is clearly marked for convenient optical path alignment by users.
