MARS MW 320x256
Close
The Sofradir staring snapshot 320 x 256 Mid Wave (MW) Infrared Focal Plane Assemblies (IRFPA) are offered to answer the military and commercial systems requirement of band II (3-5µm) detection.
These IRFPAs take advantage of the Sofradir optimized high performance, stable, low defect density Photo-Voltaic HgCdTe technology for staring arrays.
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
- Integrated Detector Dewar Cooler Assembly (IDDCA) with miniature Stirling-cycle rotary cooler, for compact, low power configuration.
On-request configurations
- IDDCA with split Stirling-cycle linear cooler, for expanded lifetime & system integration facilitation.
