Tydex offers a new product!
Diffraction gratings produced by Tydex are intended for spectral measurements in THz frequency range. They are relief-phase transmission gratings. Regular structure of such gratings is created by cutting parallel dashes (grooves) into a transparent substrate. The substrates are made of materials transparent in THz range, such as TPX (polymethylpentene) and ZEONEX (cyclic olefin polymer).
