Sofradir, a developer and manufacturer of advanced infrared detectors for military, space and industrial applications, has demonstrated its new Avalanche Photodiode (APD) mid-TV format IR detector for amplifying low input signal.
“We see our MCT Avalanche Photodiode 30 micron pitch IR detector offering customers a flexible solution to address emerging opportunities in IR applications where input light signals are very low,” says Philippe Tribolet, VP R&D, Technology and Products at Sofradir. "The low-noise APD IR detector offers system integrators a choice of wavebands, more compact optics and an ability to overcome any low input signal Read-Out Integrated Circuit (ROIC) performance degradation.”
Designed for military applications, active imagery (laser gated imaging), spectrometry, gas detection and a range of scientific applications, Sofradir’s APD 30 micron pitch IR detector made with Mercury Cadmium Telluride (MCT) technology enables users to operate cameras with small apertures or with narrow wavebands in extreme low light detection.
Sofradir’s APD IR detector can amplify low input signals by a factor of 5,300 keeping the photodiode signal to noise level constant, a result unmatched by competing technologies the company says.
The announcement further expands Sofradir’s large portfolio of high-performance, high-volume MCT IR detectors in the short-waveband (1 - 2.5 micron), and mid-waveband (3 - 5). It can be used for active imagery (2D or 3D). It can also be used for passive imagery, where low input signals are amplified.
Sofradir develops and manufactures advanced infrared detectors (IR) for military, space and commercial applications. It specializes in cooled IR detectors based on a sophisticated high performance technology, Mercury Cadmium Telluride (MCT), and its vast product portfolio of scanning and staring arrays covers the entire infrared spectrum. Sofradir also offers QWIP detectors developed in cooperation with Thales.
Sofradir owns two subsidiaries: ULIS, of which GE Equity has 15 per cent ownership, and Sofradir EC. ULIS is a high volume manufacturer of infrared detectors for low-cost IR cameras for industrial, professional and security applications. Sofradir EC develops and supplies infrared equipment for scientific, industrial, public safety, security and defense applications.
Customers for the group include the US Army, Thales, Sagem, Selex, Thales Alenia Space, ESA (European Space Agency) and FLIR Systems.
Sofradir’s headquarters are located in Châtenay-Malabry, near Paris, France. Its manufacturing facilities and those of ULIS are located in Veurey-Voroize, near Grenoble, in France. Sofradir EC is based in Fairfield, NJ (USA). Sofradir, ULIS and Sofradir EC employ more than 500 people. Total sales in 2008 were in the order of EUR 120 million (USD 150 - 160 million).
