The high speed G10768-1024D InGaAs
linear image sensors and the C10854 multichannel detector head from
Hamamatsu Photonics have been designed to meet increasing industrial
requirements for the detection of foreign bodies on-line in the near
infrared range (wavelength range from 800 nm to 1700 nm).
The G10768 devices feature 1024
individual InGaAs photodiode pixels, combined with a low noise CMOS
trans-impedance amplifier and multiplexor readout circuit, to simplify
operation. In addition, a selectable feedback capacitance is available,
allowing to choose the on-chip gain to increase dynamic range. The
device has a pitch of 25mm and is capable of very high speed readout
rates, in excess of 40,000 lines per second.
The C10854 allows easy
operation of the G10768, offering a high-speed readout, single +5 V
supply voltage, 16-bit AD converter and simple CamerLink interface. Not
only is the combination of the G10768 series and C10854 more cost
effective, but also it is smaller than many other products on the
market, says the manufacturer, making it more suited for integration
into an existing system.
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, re-cycling 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.
