Not only does it excel in the transmission of terahertz waves, but it also has low surface loss and is transparent to visible light.
"Tsurupica(R)" is a terahertz optics that has a clear advantage compared to conventional terahertz transmission materials such as high-density polyethylene and silicon. When applied to detector windows, it allows for visual confirmation of the sensor's position and status. Please feel free to contact us if you have any inquiries. 【Features】 ■ Transmission frequency: 1–12 THz ■ No strong phonon absorption typical of polyethylene, showing good transmission characteristics across the low-frequency terahertz range ■ Refractive index ~1.52 @ 633 nm, THz band ■ The refractive indices of terahertz waves and visible light are nearly equal, allowing the use of visible lasers as guiding light for optical axis confirmation *For more details, please download the PDF or contact us.
