The MPPC module is a photon counting module capable of low-light-level detection. This module consists of an MPPC device, current-to-voltage converter circuit, high-speed comparator circuit, high-voltage power supply curcuit, temperature-compensation circuit, counter circuit, and micro-computer.
The MPPC module is designed to extract maximum MPPC performance and so yields excellent photon counting characteristics. The MPPC module is expected to open up new applications in the photon counting region, including fluorescence measurement, DNA analysis, environmental chemical analysis, high-energy physics experiments, and many other fields. |
