產品系列說明

  • 對最大5mm的光束具有最大的耦合效率
  • 與氦氖雷射輕鬆搭配使用
  • 適用於2 - 12μm 範圍

Zinc Selenide Infrared (IR) Focusing Objectives are designed to provide maximum coupling efficiency between the output from an IR source and a single-mode or multi-mode transmitting fiber optic. The aspheric design provides a focal spot smaller than the fiber core diameter, allowing for precision alignment without negatively impacting transmission between the objective and fiber. Zinc Selenide Infrared (IR) Focusing Objectives are available with multiple anti-reflection (AR) coating options between 3.25 – 9.5μm, and are ideal for a range of fiber coupling and IR focusing applications.
