TECHSPEC® 硒化锌 (ZnSe) 非球面透镜的设计旨在为 10.6µm CO2 激光器提供衍射极限的聚焦性能。这些透镜由 Coherent® 红外硒化锌材料制成，在 10.6µm 波长上的体吸收系数为 <0.0005 cm-1，并具备无镀膜或宽带抗反射镀膜选项，在 8 - 12µm 范围内可提供极佳的透射率。其精密设计使其成为集成到激光系统，热成像组件和 FTIR 器件的理想选择。TECHSPEC® 硒化锌非球面透镜在 10.6µm 波长上的不规则性为 <λ/20，表面质量为 40-20，表面粗糙度 <50Å。


  • 由爱特蒙特光学设计，Coherent® 材料制成

  • 优质等级的硒化锌材料

  • 可提供无镀膜或宽带 8-12µm 抗反射镀膜选项
