Paper Abstract

Sofradir is involved in the manufacturing of the detector for PRISMA mission. Thanks to this experience, Sofradir has extended its Visible-Near infrared technology, called VISIR. This technology has the huge advantage to enable detection in both visible range and SWIR detection range (0.4μm up to 2.5μm). This 1000x256 array has been especially developed and dedicated for hyperspectral application. MCT Technologies at Sofradir covers also MWIR and LWIR infrared ranges for many years. Detectors for space applications have been already developed and validated and are currently running. For example, 1000x256 or 500x256 arrays 30 μm pitch (called Saturn or Neptune detectors) have already been validated in terms of irradiation behavior, thermal cycling, and ageing. Sofradir is now able to present a large MWIR or LWIR 1016x440 array with a 25μpixel pitch. This detector is also dedicated to hyperspectral application. Thus, with this new detector, Sofradir covers infrared ranges from Visible to VLWIR. After a brief reminding of the current VISIR focal plane array [1], and latest results from this detector, we will present in this paper the 1016x440 new array. The architecture and functionalities of this 1016x440 array will be presented and also the proposed packaging for this detector. Then, main general required performances and previous electro-optical characterizations will be also described.
