Image sensor scans at 40,000 lines per second

Hamamatsu Photonics is introducing the high-speed G10768-1024D InGaAs linear image sensors and C10854 multichannel detector head to meet increasing industrial requirements to measure foreign bodies on-line in the near-infrared range (wavelength range 800-1700nm).

The G10768 devices feature 1024 individual InGaAs photodiode pixels, combined with a low-noise CMOS trans-impedance amplifier and multi-plexor readout circuit, to simplify operation. In addition, a selectable feedback capacitance is available, providing a choice of on-chip gain to increase dynamic range. The device has a pitch of 25um and is capable of very high speed readout rates, in excess of 40,000 lines per second.

When used with the C10854 multichannel detector head, the G10768 becomes a very powerful tool. The C10854 allows easy operation of the G10768, offering a high-speed readout, single +5 V supply voltage, 16-bit AD converter and simple Cameralink interface. Not only is the combination of the G10768 series and C10854 more cost-effective, but also it is also said to be smaller than many other products on the market, making it more suitable for integration into existing systems.

Applications for the G10768 and C10854 are found in on-line infrared inspection of products, including process monitoring, foreign body detection - such as fragments of glass - recycling and sorting of different plastic materials by near-IR spectroscopy, analysis of sugars, proteins and fats for in-line food inspection, petrochemical analysis, and many more.
