| Description | Specac provide Free-Standing Wire Grid Polarizers for Far-Infrared and Terahertz (THz) polarizing applications.
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 Specac provide Free-Standing Wire Grid Polarizers for Far-Infrared and Terahertz (THz) polarizing applications.
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. Operating wavelengths are from 20 µm to 10 mm.
Features:
- High degree of polarization: >99.9%
- High transmission efficiency - No beam deviation or dispersion
- Custom frame sizes and shapes
