640 InGaAs VGA Area Sensor

GH-SW640 InGaAs area image 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 detector can be supplied in two types of metallic package:

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.
