Fiber to LN Cooled MCT Detector Couplers

Main features:

  • Efficient coupling of fiber cable to MCT/ InSb detector installed inside LN-cooled Dewar with side window
  • Mirror optics enable work in broad spectral range
  • Pre-aligned and adjustable to maximize coupling efficiency
  • SMA or FC/PC (on request) adaptor for infrared fiber optical cable.
  • Compatible with Chalcogenide and Polycrystalline IR-Fiber Cables


Refocusing couplers for Dewar devices from art photonics GmbH enable easy coupling of detachable mid IR-fiber optical cables to MCT/ InSb detector installed inside LN-cooled Dewar with side window. art photonics GmbH presents two versions of Dewar couplers: Lens Refocusing coupler for Dewar device and Mirror Refocusing coupler for Dewar device.

The simplest lens coupler is a standard or customized construction which is fixed on the side window of LN-cooled Dewar. Adjustable in 3 dimensions - X-Y for the lens & Z - for connector position.

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

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

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