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).

The gratings are manufactured in four standard options for the following transmission bands within the 0.3-3 THz range: 0.28–0.55 THz; 0.49–0.98 THz; 0.87–1.75 THz; 1.56–3.12 THz.
Gratings for other bands within 0.3-3 THz range can be manufactured at customer’s request.
