铜涂层石英光纤

铜涂层石英光纤

art photonics的铜合金涂层石英光纤是高温、真空和恶劣环境条件下应用的最佳解决方案之一。铜合金涂层光纤具有石英光纤的所有优点。与聚合物涂层光纤相比,其他显著优点包括优越的机械强度和更好的抗疲劳性能。传输范围从220到2400nm取决于紫外或近红外石英纤芯的选择。工作温度范围为-270°C至600°C;湿度高达100%。

主要特点:

  • 工作温度高达600°C
  • 优良的机械强度和柔韧性
  • 在高真空条件下不放气
  • 可焊接到连接器中(无环氧树脂选项)
  • 沿金属涂层的有效散热量
  • 蒸汽、ETO、蒸汽、电子束或伽玛灭菌
