这款 LPDM 长通二向色镜旨在反射近红外 (NIR) 光，同时为较长的近红外和短波红外 (SWIR) 波长提供高效传输。

它非常适合激光束合束和路由，尤其是在使用 980 nm 或 1064 nm 激光的系统中。该反射镜能有效反射这些常见的近红外激光线，同时允许在 1200-1800 nm 范围内传输信号，使其成为涉及 InGaAs 传感器、光纤通信或红外荧光的应用的关键组件。

主要规格：

  • 波长/主要规格：针对 SWIR 传输和 NIR 反射优化的长通过渡。
  • 带宽/过渡规格：反射 900–1100 nm；传输 1200–1800 nm。
  • 透射率/阻挡：T >90% @ 1200–1800 nm；R >99% @ 900–1100 nm。
  • 格式/定制选项：提供安装（直径 12.5–25 mm）和未安装（25x36–35x52 mm）格式；可根据要求提供定制尺寸。

产品常见问题

二向色镜有什么作用？

分色滤光片按波长分离光线。它被设计用来反射某个波长范围的光线，同时透射另一个波长范围的光线。

例如，分色滤光片可以反射激光波长，同时透射可见对准光束、荧光信号或另一个激光波长。其确切功能取决于反射带、透射带和入射角。
我应该使用什么入射角？

大多数分色镜都是为特定的入射角而设计的，通常为 45°，除非另有说明。
这种二向色镜可以用来组合或分离激光束吗？

是的。当波长差异足够大且反射/透射波段与系统要求匹配时，二向色镜常用于激光束合成和分束。

例如，一个波长可能以45°反射，而另一个波长则穿过镜片。订购前，请确认激光波长、入射角、光束尺寸以及所需的反射/透射性能。
