InGaAs Image Sensor

InGaAs Image Sensor

SYTOPHOTONICS InGaAs image sensors (Indium Gallium Arsenide sensors) are high-performance infrared imaging components designed for near-infrared and short-wave infrared (SWIR) applications. Available in both area array and linear configurations, these sensors deliver high sensitivity, low noise, and reliable imaging performance for advanced detection systems.

With a standard spectral response range of 0.9–1.7 μm and extended InGaAs options covering 0.4–1.7 μm, InGaAs linear image sensors and detectors provide precise imaging solutions for applications requiring enhanced sensitivity beyond the visible spectrum.
