US InGaAs Camera: Advanced Imaging for Infrared Applications
US InGaAs cameras are infrared imaging devices that use Indium Gallium Arsenide (InGaAs) sensors, primarily designed and manufactured or distributed in the United States. These cameras are widely used for capturing images in the shortwave infrared (SWIR) spectrum, typically ranging from 900 nm to 1700 nm, and are critical in industries such as defense, aerospace, semiconductor inspection, surveillance, telecommunications, and scientific research.
📷 What Is an InGaAs Camera?
An InGaAs camera uses a sensor made of indium gallium arsenide, a semiconductor material sensitive to near-infrared (NIR) and SWIR light. Unlike traditional silicon-based cameras (limited to visible and NIR up to ~1000 nm), InGaAs cameras can image in the SWIR band, making them indispensable for low-light, non-visible, and through-obscurant imaging applications.
