GH-SW320 SWIR Sensors are two-dimensional image sensors that have a hybrid structure consisting of a CMOS readout circuit (ROIC: readout integrated circuit) and back-illuminated InGaAs photodiodes for short wavelength infrared (SWIR, 900nm-1700nm) and extended wavelength infrared (Vis-SWIR, 400nm-1700nm) regions.
The InGaAs imaging detector can be supplied in two types of metallic packages:
Nitrogen & Vacuum, which both include a Thermo-Electric Cooler (TEC)
It is well-adapted to a large range of applications, such as surveillance, hyperspectral imaging, remote sensing, machine vision, industrial sorting, process inspection, and science.
The GH-SW320 InGaAs VGA Area Sensor offers high-resolution imaging with state-of-the-art InGaAs linear image sensor technology, optimized for short-wavelength detection. Featuring a sophisticated read-out integrated circuit (ROIC), this SWIR sensor ensures precise and reliable performance. For more detailed information, please refer to the following chart.
