Safran-Sagem counts among the system-level equipment makers selecting Daphnis HD MW in order to meet end-customer demands for more recognition and identification ranges on optronic products.
“High-end optronic equipment is required to carry increasingly more functions in constrained volumes. From this standpoint, the reduction in pixel pitch size of Daphnis FPA enables improved performance across all dimensions of an ISTAR mission: information, surveillance, target acquisition and reconnaissance without compromising the compactness of the optronic product. This is another strong market request,” said Thierry Dupoux, R&T director at Safran-Sagem.
Whereas visible imaging systems (which use shorter wavelengths than IR wavelengths) have been using HD formats for several years now, the transition to the HD format in IR wavelengths (3 to 5 µm) has just begun to take place. In that respect, Daphnis’ 4.8µm spectral cut off wavelength is a key differentiator, which allows unsurpassed signal over noise ratio, even in a low temperature scenario.
“Thanks to the sharp square like profile of its Mercury Cadmium Telluride photodiode and enlarged MW band, DAPHNIS offers improved recognition range versus any competing 10µm pitch products we have recently seen introduced in the market” said Laurent Fullana, general manager at Sofradir. “This elevates DAPHNIS to the product of choice for applications like gimbals, high-end vehicles sights and infrared search and track systems. Moreover, the ability to obtain an HD image format from a detector whose size fits previous platform generations is a real benefit as it facilitates customer system upgrades.”
Daphnis-HD MW brings a wider field of view, longer-range capabilities and all-important higher resolution to elite military equipment. Key features:
Sofradir is the leading developer and manufacturer of key classes of advanced infrared (IR) detectors for military, space, scientific and industrial applications. Its vast IR product portfolio covers the entire spectrum from the visible and near infrared to very far infrared. Sofradir pioneers developments in cooled IR detectors based on a sophisticated high performance technology: Mercury Cadmium Telluride (MCT), to which Sofradir has added Indium Antimonide (InSb), Indium Gallium Arsenide (InGaAs) and Quantum Well Infrared Photodetector (QWIP) technologies. Many of the world’s system makers use Sofradir’s military-grade, battlefield proven IR detectors for missile seekers, targeting pods, armored vehicle sights, handheld thermal imagers and other airborne, naval and ground vehicle applications. Sofradir is the leading European manufacturer for IR detectors deployed in space.
Founded in 1986, Sofradir is headquartered in Palaiseau, near Paris. It carries out research and development as well as high volume manufacturing at two facilities: Veurey-Voroize, near Grenoble, and Palaiseau, near Paris. Sofradir owns two subsidiaries: ULIS, a high volume manufacturer of microbolometers based in Veurey-Voroize and US-based Sofradir-EC, a provider of uncooled and cooled IR imaging cores and engines, located in Fairfield, New Jersey. Together Sofradir, ULIS and Sofradir-EC employ about 800 staff.
