作为光通信领域所开发的石英系列光纤的工作波长，尽管用在较短的传输距离，也只能用于2pm。为此，能在更长的红外波长领域工作，所开发的光纤称为红外光纤。
红外光纤（Infrared Optical Fiber）主要用于光能传送。例如有：温度计量、热图像传输、激光手术刀医疗、热能加工等等。

IRphotonics is a leading manufacturer of specialty fiber. We manufacture mid infrared (MIR) optical fibers and materials that can be customized for specific wavelengths and applications that include sensing, telecommunications, spectroscopy, medical laser and industrial high-power beam delivery among others. Our fluoride ZBLAN technology is an ideal replacement for most Erbium Yag (Er:Yag) or Holmium (Ho:Yag) applications currently using chalcogenide or sapphire optical fibers. Using our enhanced patented Fluoride Fiber manufacturing technology as well as our unique chemical compositions, IRphotonics Inc. leads the industry in providing quality glass and fiber at the lowest cost.
