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.
