Tydex Thz Wire‑Grid Polarizer
Product Introduction：
For radio‑frequency and terahertz ranges, this wire‑grid terahertz polarizer enables polarization of radiation at wavelengths from 150 μm up to several centimetres. It consists of parallel tungsten wires with a thickness of 11 μm, mounted on a substrate‑free holder.
Applications：
THz spectroscopy, THz microscopy, Sensors and detectors, Fourier‑transform spectroscopy, THz and SHF polarimetry
Features：
Capable of withstanding high‑energy incident radiation; Provides high transmittance for the desired polarization thanks to the substrate‑free design;
Delivers a high degree of polarization;
Constructed from tungsten wires;
Mounted in a holder fitted with a protective ring marked with the wire‑grid orientation.
Advantages of Wire‑Grid Terahertz Polarizers over Polypropylene‑Grid Polarizers：
Superior transmission of the desired polarization due to the substrate‑free design; Capable of withstanding high‑intensity radiation.
