Polarization Modulators

EEOptics Corporation's Polarization Modulator provides a continuous rotation of any polarized light with the applied control voltage in high modulation rate. The device is developed based on EEO crystals and can rotate State of Polarization (SOP) through phase retardation. Polarization rotators, Phase Modulators and Intensity Modulators are also available.
