Fiber Couplers for LN Cooled MCT Detector

Main features:

  • Efficient coupling of fiber cable to MCT/ InSb detector  in side window Dewar  
  • Wide-range operation thanks to Mirror optics
  • Price effective Lens optic version 
  • Pre-aligned and adjustable  for maximum coupling efficiency
  • SMA or FC/PC  adaptor for fiber (Chalcogenide and Polycrystalline)  optical cable

Description

Refocusing couplers are designed  for  easy coupling of  mid-IR fiber optical cables to MCT/ InSb detector  in LN-cooled side window Dewar.   Art photonics  presents two versions:  Lens Refocusing- and Mirror Refocusing coupler.

The simplest Lens  version coupler can be  standard or customized. Adjustable in 3 dimensions - X-Y for the lens and Z - for the connector position.

Advanced version of the coupler is based on pre-aligned parabolic mirrors. This version serves to eliminate chromatic aberrations and has purging option to avoid atmospheric disturbance in spectral details of the object.  Adjustable in 3 dimensions - X-Y for the mirror and Z - translation of the Dewar.

Both couplers have SMA or FC/PC (on request) adaptor for  fiber optical cable.

See product pages of  our Chalcogenide and Polycrystalline Fiber cables for different spectral range detectors and radiation sources.
