Sofradir infrared detector products: the past and the future

摘要

Sofradir has developed 2nd and 3rd generation InfraRed (IR) detectors sensitive in different wavebands covering the 1 to 16 μm spectral range. The main material used for cooled IR detector is HgCdTe and Sofradir extends its product range using QWIP for 8-9 μm large staring arrays and microbolometers based on amorphous Silicon (Si:α) thermometer material for uncooled technology. Array characteristics and performances are presented (including new results) and the maturity of technologies and products are discussed for present as well as for short term production activities.
