Zinc Selenide Infrared (IR) Focusing Objectives and Collimators were designed by art photonics to provide maximum coupling efficiency between the output from Mid-IR lasers and our chalcogenide and polycrystalline optical fibers. The aspheric design of focusing objectives provides a focal spot smaller than the fiber core diameter, allowing for precision alignment.

Zinc Selenide Infrared (IR) Focusing Objectives and Collimators are available with multiple anti-reflection (AR) coating options between 3-5µm or 8-12μm, and are ideal for a range of fiber coupling and collimating applications.
