2-inch Liquid Crystal Variable Retarders, Half-Wave, with Compensation
The LBTEK 2-inch Half-Wave Compensated Liquid Crystal Variable Retarder is coated with corresponding anti-reflection coatings within the operating wavelength range of 400-700 nm, 700-1100 nm, or 1100-1650 nm. Under the control of an external AC voltage (DC voltage not allowed), it can achieve flexible adjustment of retardation between 0 nm and λ/2.
It features a clear aperture of Ø20 mm, mounted in a mechanical housing with attached wiring. The mechanical housing is compatible with Ø2-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.
