PEMs are made of isotropic optical materials and operate at a resonant frequency. Unique properties of the PEM include:
- polarization purity
- large aperture
- high power handling capability – up to 5 GW/cm2 for some devices
- large acceptance angle
- wide range of models for different spectral regions, from vacuum UV to Terahertz
- retardation stability
- durability – some PEMs are still in use from 1977!
