Product Introduction:
For radio frequency and terahertz ranges, this wire grid polarizer can radiate polarization in the wavelength range of 150 µ m to several centimeters. They are made of 11 µ m thick flat tungsten wire and installed on a bracket without a substrate.
Application:
Terahertz spectroscopy Terahertz microscope Sensors and detectors Fourier transform spectroscopy THz and SHF polarization methods.
features:
Capable of withstanding high-energy incident radiation Due to the absence of a substrate, it can provide high transmittance for the required polarization Provide high polarization Made of tungsten wire Installed on the bracket (protective ring marked with wire grid direction)
Wire grid polarizerRelative polypropylene grid polarizerAdvantages:
Due to the absence of a substrate, the required polarization can be transmitted more effectively Can withstand high-intensity radiation.
