Description

The Liquid Crystal Polarization Rotator is a highly useful optical component that effectively and achromatically rotates the polarization of light. It uses Liquid Crystal twisted nematic technology to rotate the orientation of linear polarization by a fixed amount of typically 45° or 90°. 
    
The device has a wide acceptance angle and functions over a very large spectral range from VIS to NIR, making it less expensive than quartz retardation plates, which are typically used for polarization rotation. Additionally, by applying a voltage on the TN cell, the Polarization rotation can be "switched off".
