Sofradir introduces new InSb infrared detector array

Châtenay-Malabry, May 6th, 2014 – Sofradir will introduce its new cryo-cooled Axir infrared detector array at SPIE’s Defense, Security & Sensing show in Baltimore MD, May 6-8. The new Axir detector follows the company’s 2013 acquisition of InSb technology from Sagem, one of its parent companies. Sofradir developed and certified this new infrared detector technology in just one year following the launch of the product. Sofradir offers a state of the art product, taking benefit of its hybridation know-how and expertise of R&D people.

The new Axir detector is based on a VGA format 15μm pixel pitch InSb FPA and is designed to operate optimally in extremely harsh environments. The detector is highly sensitive in the mid-wave (MWIR) spectral band ideal for certain ground, naval and airborne defense applications. InSb technology offers the capacity to deliver high resolution and sensitivity to enable the detection and identification of the targeted area to be vastly expanded, hence achieving a better perception of the battlefield.


Perfect mastery of InSb technology

Sofradir has been able to leverage its significant expertise in cryogenically cooled infrared detector technology to quickly master the benefits of InSb technology including: high repeatability through thermal cycling and excellent uniformity due to defect-free production and low pixel dispersion.

Philippe Bensussan, Chairman and CEO of Sofradir, comments “Developed in less than a year, the new Axir infrared detector demonstrates the perfect mastery of InSb technology by our Sofradir teams. The Axir infrared detector features exceptional stability, simplifying the implementation of the detector within the final system. It is the perfect complement to the infrared detector technologies offered by Sofradir.”


The first Axir detector applications

Axir will be used in systems with demanding operability, such as fire control missiles, specific surveillance systems and Enhanced Vision Systems (EVS) for military and commercial aircrafts.

Introduced for the first time in Baltimore, Sofradir’s Axir detector is already available.


About Sofradir

Sofradir is the world leader in the design and manufacture of high-tech infrared detectors towards military, space and industrial applications. Its vast range of IR products covers the entire visible spectrum and from the close to distant infrared spectrum. Sofradir is constantly innovating in the development of cooled IR detectors using high-performance technologies based on mercury cadmium telluride (MCT) as well as other technologies such as indium antimonide (InSb), indium gallium arsenide (InGaAs) and the quantum-well infrared photo detector (QWIP). A number of missile homing systems, airborne targeting pods, cameras for armoured vehicles, portable binoculars and other applications on land-based, naval and airborne vehicles utilise Sofradir’s combat proven products. Sofradir is uniquely positioned in Europe as the only manufacturer of IR detectors approved for applications in space.

The head office of Sofradir, founded in 1986 in France, is located at Châtenay-Malabry. Mass production is carried out at Veurey-Voroize, near Grenoble. A new head office and production site is currently being built at Palaiseau in the vicinity of Paris. Sofradir owns two subsidiaries: ULIS, manufacturer of microbolometers based at Veurey-Voroize and Sofradir EC, supplier of IR modules, located in Fairfield, New Jersey, USA. Sofradir, ULIS and Sofradir EC employ about 700 people with combined turnover of $240 million in 2013.


Sofradir will present its new developments in IR from 5th to 9th May 2014 at the SPIE DSS in Baltimore, stand no. 809
