can change the light polarization state of the modulation device, can make the Transmission light produce dynamic Phase retardation. The device through the light part is made of isotropic material, work with inherent resonant frequency periodic vibration, due to the photoelastic effect, Optics material Refractive Index will be periodic changes, thereby changing the incident light Phase delay. Our PEM has the advantages of large acceptance angle, large optical aperture, wide Wavelength range, high modulation frequency and high precision. According to the working mode, our PEM can be divided into one and two types. The one-dimensional PEM has only one vibration dimension and is applicable to UV(355nm), visible and Near Infrared (NIR) bands; the two-dimensional PEM has two vibration dimensions and can achieve a wider range of Phase modulation, mainly applied to visible and infrared bands.
