Japan InGaAs Cameras: Leading the Infrared Imaging Frontier
Japan stands as a global leader in advanced imaging technologies, and one of its most specialized segments is the development of InGaAs (Indium Gallium Arsenide) cameras. These cameras are uniquely suited for near-infrared (NIR) and short-wave infrared (SWIR) imaging applications, making them essential tools in sectors ranging from semiconductor inspection to defense and scientific research.
What is an InGaAs Camera?
An InGaAs camera uses a sensor made from Indium Gallium Arsenide—a semiconductor material that is sensitive to wavelengths ranging from approximately 900 nm to 1700 nm, well beyond the range of standard silicon-based sensors. This makes them ideal for capturing images in low light, through certain materials, and in specialized industrial settings.
