VEGA LW 384x288

The Sofradir staring snapshot 384x288 Long Wave (LW) Quantum Well Infrared Photodetector (QWIP) is offered to answer the compact applications (FLIR, IRST, reconnaissance, surveillance,
airborne camera,…) in the band III (8 – 9 µm) detection.

Hybridized on an Indigo ISC0208 CMOS Read-Out Integrated Circuit (ROIC), the AlGaAs QWIP array can be offered in various long vacuum-life Dewar and Cooler configurations, in order to meet the different mechanical and cooling needs of the systems.

Standard configurations

- Integrated Detector Dewar Cooler Assemblies (IDDCA) with miniature Stirling-cycle rotary coolers, for compact, low power configuration.

On-request configurations

- IDDCA with split Stirling-cycle linear cooler, for expanded lifetime & system integration facilitation.
