- Wide wavelength range (20 µm to 10 mm)
- High degree of polarization; >99.9%
- High transmission efficiency
- No beam deviation or dispersion
- Choice of materials and mounting configurations
These polarizers consist of an array of parallel 5 μm or 10 μm tungsten wires secured to a 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. There is no use of substrates, so the performance is dependent on the diameter and spacing between wires. Operating wavelengths are from 20 μm to 10 mm; ideal for mid-infrared (MIR), far-infrared (FIR), and terahertz (THz) applications.
