Refocusing and Collimating Fiber/Lens Objectives

Refocussing & Collimating Fiber/Lens Objectives can be used with polycrystalline fiber cables (4-18 μm spectral range) and chalcogenide fiber cables (1-6 μm spectral range).

  • Compatible with SMA-terminated fiber cables
  • NA=0.35, pupil diameter 15 mm
  • Refocusing or collimating design
  • Focusing of collimating beam into the fiber
  • Collimation of output beam from a fiber
  • Fiber end imagination to detector/emitter element
