New InGaAs Area Image Sensor for Hyperspectral Cameras

Hamamatsu Photonics has developed an InGaAs area image sensor for hyperspectral cameras capable of detecting short-wavelength-infrared light up to 2.55 µm, which is the world’s longest wavelength detectable by this type of area image sensor.

By applying compound opto-semiconductor manufacturing technology fostered in-house over many years, we designed and developed a new area image sensor G14674-0808W made of indium gallium arsenide (InGaAs). It is capable of detecting short-wavelength-infrared light up to 2.55 µm (micrometers or one millionth of a meter) which is the world’s longest wavelength detectable by this type of area image sensor. Installing this new InGaAs area image sensor into hyperspectral cameras for plastic recycling will boost the recycling rate since hyperspectral cameras can screen and sort plastics containing flame-retardant resin to separate them out from other plastics, which has been extremely difficult up until now. Hamamatsu will start accepting orders from domestic and overseas industrial camera manufacturers on July 1, 2019.

This new InGaAs area image sensor will be on display at the IMAGE SENSING SHOW 2019, held in Pacifico Yokohama (Nishi-ku, Yokohama, Japan) for 3 days from June 12 to June 14, where domestic and overseas manufacturers and experts in image processing devices and sensing technology gather to exhibit and explore new technology.
