Hamamatsu Photonics has developed an InGaAs area image sensor for hyperspectral cameras capable of detecting short-wavelength-infrared light up to 2.55 µm: the longest wavelength detectable by this type of area image sensor. Hamamatsu have used compound opto-semiconductor manufacturing technology to produce the new G14674-0808W area image sensor made of indium gallium arsenide (InGaAs). If used in hyperspectral cameras for plastic recycling, it will increase the recycling rate plastics containing flame-retardant resin can be separated from other plastics.
