PDC Series
The PDC is an electronic carrier module that can operate any silicon avalanche diode suitable for Geiger mode operation (with up to 480V breakdown voltage BV). To achieve the desired trade-off between quantum detection efficiency and dark counting rate, the over-voltage above breakdown voltage is adjustable from 5V to 24V.
A fast timing electronic board fully exploits the device performance in photon timing. By means of an easily configurable Peltier controller the module can operate devices mounted on a cooler with a temperature sensor (NTC or PTC). The detector device is protected from overheating (e.g. in case of daylight illumination) by a built-in monitor of current and temperature.
A patented integrated Active Quenching Circuits (iAQC), specifically designed and optimized for photon counting applications, makes the PDC ideal for portable equipment and for all applications requiring low power consumption.
