Features
- Designated for detachable IR-fiber optical cables with SMA-termination
- Adjustable in 3d dimensions – X-Y for lens & Z – for connector position
- Can be fixed at side window Dewar for QCL / TDL lasers & MCT/ InAs detectors
Standard or customized coupler construction can be supplied for customer laser or detector installed inside LN-cooled Dewar with side window. CIR- or PIR-fiber optical cable with SMA-termination can be supplied according customer specification for his specific applications. 2 types of MCT-detectors are also 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.
