WebbSensors Unlimited, Inc. produces NIR and SWIR cameras and arrays - all based on InGaAs imaging technology - that see beyond the visible wavelength spectrum. WebbSWIR is the acronym for shortwave infrared and refers to non-visible light falling roughly between 1400 and 3000 nanometers (nm) in wavelength. The visible spectrum ranges from 400nm to 700nm, therefore SWIR light is invisible to the human eye. In order to detect SWIR wavelengths, we need dedicated sensors made of In GaAs (Indium Gallium ...
