Tydex Microwave Wire‑Grid Polarizer2‑300 GHz
Product Introduction：
For the microwave‑terahertz range, this wire‑grid polarizer is designed for radiation polarization between 2‑3 GHz and 300 GHz. It consists of parallel tungsten wires with a thickness of 20 µm, mounted on a substrate‑free holder.
Applications：
Spectroscopy; Polarimetry; Astronomy; Antenna Engineering.
Features：
Capable of withstanding high‑energy incident radiation; high transmittance for the desired polarization thanks to the substrate‑free design; delivers a high degree of polarization; constructed from tungsten wires; mounted on a holder with a protective ring marked with the wire‑grid orientation.
Advantages of Wire‑Grid Polarizers over Polypropylene‑Grid Polarizers：
Owing to the absence of a substrate, improved transmission is obtained for the desired polarization, and high‑intensity radiation can be tolerated.
