VENUS LW 384x288

The Sofradir staring snapshot 384 x 288 Long Wave (LW) Infrared Focal Plane Assembly (IRFPA) is offered to answer the compact military and commercial system requirements of band III (8-12 µm) detection.

This IRFPA takes advantage of the Sofradir optimized high performance, stable, low defect density Photo-Voltaic (PV) Mercury Cadmium Telluride (HgCdTe) technology for staring arrays, with detective material bandgap adapted for LW applications.

Hybridized on a Sofradir state of the art CMOS Read-Out Integrated Circuit (ROIC), this IRFPA 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

- 9.5µm cut-off Integrated Detector Dewar Cooler Assemblies (IDDCA) with miniature 0.5W Stirling-cycle rotary coolers, for compact, low power configuration.
