Hamamatsu unveils Ingaas sensor and detector head

The products have been designed to meet increasing industrial requirements for measuring foreign bodies online in the near-infrared (IR) range (wavelength range from 800nm to 1,700nm).

The G10768 devices features 1,024 individual Ingaas photodiode pixels, combined with a low-noise complementary metal oxide semiconductor (CMOS) trans-impedance amplifier and multi-plexor readout circuit, which is claimed to simplify operation.

A selectable feedback capacitance is also available, allowing choice of on-chip gain to increase dynamic range.

The device has a pitch of 25mm and is capable of high-speed readout rates in excess of 40,000 lines per second.

The C10854 is said to facilitate operation of the G10768, offering a high-speed readout, a single +5V supply voltage, a 16-bit AD converter and a Camerlink interface.

The combination of the G10768 series and the C10854 is, according to the company, a cost-effective solution and is also smaller than many other products on the market, making it more suited for integration into an existing system.

Applications for the G10768 and the C10854 are found in online IR 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 inline food inspection; and petrochemical analysis.
