Theory & Technical Info

Polarization of light can be achieved in a variety of ways. The relative efficiency of the polarization will depend on the method of polarization and the wavelength. The established methods of making polarizers include photo-lithography, holography, ruled grating, free standing wires, bire-fringence, dichroic glasses, dielectric coatings and brewster angle plates. Specac manufactures polarizing components using a number of these methods and offers polarizers for use from vacuum UV to the far infrared. Regularly spaced thin strips of parallel conductive wires will behave as a low loss polarizer. They will transmit one component (Ts) of the incident radiation with the electric field perpendicular to the wires, and reflect the other component (Rp) with the electric field parallel to the wires, in the sub-millimeter and millimeter wavelengths.
