FLIR Systems, which has long concentrated on its mature InSb FPA technology has been internally developing Type 2 Superlattice (T2SL) FPAs for use in future products.The company, which has been part of the VISTA consortium, is making use of the InAs/GaSb epitaxial structures that have been developed by JPL and NRL under the VISTA program and grown by IntelliEPI and IQE. It is expected that the company will soon introduce a camera core based on a HOT MWIR 640 x 512 FPA with 15 micron pixels.
Raytheon and Lockheed Martin have signed a contract under which Raytheon will provide the next-generation EO-DAS (Electro-optical-Distributed Aperture System) for the F-35 Joint Strike Fighter. The new system will make use of very large format, small pixel MWIR nBn FPAs developed by Raytheon Vision Systems (Goleta, California).
A breakthrough in the more widespread use of Type 2 Superlattice (T2SL) FPAs is about to occur. One of the largest infrared applications in the U.S. - the EO-DAS (Electro-optical-Distributed Aperture System) for the Lockheed Martin F-35 Joint Strike Fighter - is being upgraded to T2SL FPAs (from the existing large format InSb FPAs).The Air Force anticipates two potential upgrades.
