Introduction to scientific InGaAs FPA cameras
Even though light in the NIR and SWIR regions is invisible to the naked eye, its properties are quite similar to those of light in the visible (VIS) region of the spectrum. Like VIS light, NIR/SWIR light is reflective and can provide fine contrast and resolution in images acquired with an appropriately sensitive detector (e.g., an InGaAs FPA). This technical note offers an overview of InGaAs FPAs and discusses key performance features of InGaAs-based cameras for lowlight scientific imaging and spectroscopy applications in the NIR/SWIR regions of the spectrum.
