SWIR Cameras & Cores
Because standard silicon-based sensors are typically sensitive up to 1000 nm only, SWIR cameras require sensors capable of imaging beyond the upper limit of silicon. InGaAs (indium gallium arsenide) sensors are conventionally used for SWIR imaging and cover the 900 nm to 1700 nm spectral range with high quantum efficiency (typically > 70%). Recent improvements to InGaAs sensors enable imaging both visible and SWIR (400 nm to 1700 nm using SenSWIR™ technology from Sony©, for exam
