Frequently Asked Questions

The refocusing coupler is used for detachable IR-fiber optical cables with SMA-termination and can be fixed at side window Dewar for QCL/TDL lasers & MCT/InAs detectors.

The refocusing coupler is adjustable in 3d dimensions - X-Y for lens & Z - for connector position and designated for detachable IR-fiber optical cables with SMA-termination.

Yes, the coupler construction can be customized for customer laser or detector installed inside LN-cooled Dewar with side window.

Two types of MCT-detectors are available for a set with IR-cable and optical fiber coupler - either with LN-cooling in Kedal Dewar for 4-14µm or with triple Peltier cooling - for 1-6µm spectral range.

The coupler has a Ø55 mm diameter and a length of 40 mm. It has angular translation in the range ±2.50° in both orthogonal axes and a Z-translation stage in the range ± 5 mm. The lens material is Ge or ZnSe, Ø15 mm, f =10 mm, AR-coating for 10.6 µm (other wavelength - on request).
