多晶红外光纤

多晶红外光纤

art photonics开发了一种独特产品的量产技术–纤芯/包层多晶红外(PIR-)光纤,在3至18μm的宽光谱范围内透明。高性能PIR纤芯/包层光纤的挤出纤芯直径范围为240µm至860µm。不断改进的挤出工艺可提供PIR纤维优异的光学质量和机械强度。在上述光谱范围内没有吸收峰的低光损耗确保了PIR光纤成功用于广泛的应用领域。

主要特点:

  • 在3 – 18μm范围内的高透射率
  • 9 – 13 µm范围内的低光损耗约为0.2 – 0.3 dB / m
  • 芯/包层结构的芯直径范围为240至860μm
  • 老化速度慢
  • 不吸水,无毒
