The Sofradir staring snapshot 320 x 256 Very Long Wave (VLW) Infrared Focal Plane Assemblies (IRFPA) are offered to answer the military and commercial systems requirement of band III (8-12µm) detection.
These IRFPAs take advantage of the Sofradir optimized high performance, stable, low defect density Photo-Voltaic 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), these IRFPAs are 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
- 11.0 µm IRFPA at 70K into IDDCA with 1W split Stirling-cycle linear cooler.
