WebbAs you can see, all organic materials like TPX, PE, and PP have uniform stable transmission about 80 to 90% starting from ~200 µm and up to 1000 µm. Surely they excellently transmit at larger wavelengths too. Crystalline materials like silicon, quartz, and sapphire have lower transmission in THz range due to reflection losses. http://www.plasticgenius.com/2011/05/infrared-and-ultraviolet-transmission.html
