Sofradir has developed a prototype High Operating Temperature L-HOT MWIR integrated detector cooler assembly (IDCA). The L-HOT MWIR demonstrator meets system integrators requirements to reduce SWaP (Size, Weight and Power) in military equipment.
With p-on-n MCT (Mercury Cadmium Telluride) photodiode technology, Sofradir has minimised dark current while keeping the nominal 5µm cut-off wavelength. Consequently, L-HOT MWIR offers low power consumption in a full performance IR detector.
The detector has a TV format 15µm pitch and operates at 150K (-123°C), 60K higher than standard MCT IR detectors in the 3-5µm waveband, and consumes less than 2W. It achieves the same noise-equivalent temperature difference (better than 20mK) as Sofradir’s standard full performance mid-waveband IR detectors.
