Cryogenic Free-Standing Wire Grid Polarizers
Far-Infrared and Terahertz Polarizers
Specac provide Free-Standing Wire Grid Polarizers for Far-Infrared and Terahertz (THz) polarizing applications, which are suitable for use at Cryogenic tempertures. These polarizers consist of an array of parallel 5 μm or 10 μm gold-coated tungsten wires secured to an invar mounting frame with a wire spacing of 12.5 μm or 25 μm. These wires act to reflect the incident radiation electric field component parallel to the direction of the wires, and transmit the electric field component perpendicular to the wires. Operating wavelengths are from 20 μm to 10 mm.
Standard polarizer frames are circular in shape with a clear aperture of 55 mm and outer diameter of 70 mm.
