The Newport 932-CX is a single-channel liquid crystal controller that delivers precise voltage control over liquid crystal variable retarders through a 2 kHz square wave AC output with variable amplitude. The instrument enables continuous adjustment and modulation of optical attenuation in polarization-controlled systems. When polarizing optics are removed from the optical path, the 932-CX functions as a variable retarder, allowing creation of quarter-wave, half-wave, or fractional waveplate configurations by voltage adjustment.
