Hamamatsu Photonics has introduced a C11208 MPPC module that integrates the S11028 series MPPC, a pixelated silicon avalanche photodiode operated in Geiger-mode, with a highperformance thermoelectric cooler. Along with the TE cooled MPPC, the module houses a currentto- voltage converter, high-speed comparator, high-voltage power supply circuit, temperature-control and counting circuits and a micro controller.

The module gives the operator a choice of three separate signal outputs of analogue current, digital voltage or USB. The threshold level for photon detection can be controlled externally on a PC when the module is connected via a USB interface.
