Zinc Selenide Infrared (IR) Focusing Objectives

Zinc Selenide Infrared (IR) Focusing Objectives
  • Maximum Coupling Efficiency of Beams up to 5mm
  • Easy Alignment with HeNe Lasers
  • Performance from 2 - 12μm

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.
