PLUTON LW 288x4

The Sofradir 288x4 Long Wave (LW) Time Delay & Integration (TDI) Infrared Focal Plane Assemblies (IRFPA) are offered to answer the requirements of band III (8-12µm) detection of military (FLIR, IRST, surveillance,…) and commercial (spectrometry, non destructive tests,…) systems.
These IRFPAs take advantage of the Sofradir high performance, stable, low defect density Photo-Voltaic HgCdTe technology, 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 Assemblies (IDDCA) with miniature Stirling-cycle rotary coolers, for compact, low power configuration.
- IDDCA with split Stirling-cycle linear cooler, for expanded lifetime & system integration facilitation.
