Collimating and Refocusing Objectives for MID-IR Fiber Cables

Main features:

  • Compatible with SMA-terminated fiber cables
  • NA=0.35, Pupil diameter 15 mm
  • Refocusing or collimating design

Zinc Selenide Infrared (IR) Refocusing and Collimating Objectives are designed by art photonics to provide maximum coupling efficiency into chalcogenide and polycrystalline optical fibers and fiber bundles.

All lenses are available with anti-reflection (AR) coating options in 3-5µm or 8-12μm spectral ranges, and are ideal for various applications in thermal sensing, IR-imaging etc.
