InGaAs cameras are now being used to find bruising in fruit, sort plastics for recycling, and help the glass-bottle manufacturing industry detect defects. This penetration into new markets is being driven by the availability of cheaper, higher-quality InGaAs material, reports Martin Ettenberg of SUI, Part Of Goodrich Corporation.
The falling cost of InGaAs cameras is driving their increased deployment in areas as diverse as spectroscopy, object identification, and military and thermal imaging. These more affordable detectors, which operate in the spectral band between 750 nm and 2.6 µm, are just starting to be used for applications as varied as sorting plastics, determining fill levels in opaque plastic bottles and imaging under starlight conditions.
Improvements in material quality have accompanied these increases in sales, leading to devices with greater uniformity and lower dark current, and room-temperatureoperation imaging arrays with greater sensitivity. Further advances are expected to follow, fueling the trend for higher volumes, improved performance and falling prices that SUI, Part Of Goodrich Corporation. (SUI) of Princeton, NJ, has witnessed for over a decade.
