Product Introduction
Shanghai Tera photoelectric Technology offers professional customized production of THz optical lenses. They can provide dedicated off-axis parabolic mirrors, filters, polarizers, window plates, lenses, prisms, waveplates, beam splitters, reflectors and Fresnel lenses for THz applications. Additionally, they also offer THz attenuators and THz broadband phase shifters.
THz lenses are generally made of two materials: TPX and HRFZ-Si.
