The C11208 series is a photon counting module that contains a thermoelectrically cooled MPPC (multi-pixel photon counter) capable of detecting ultra-low light. Along with the thermoelectrically cooled MPPC, it consists of a current-to-voltage con-verter, a high-speed comparator, a high-voltage power supply circuit, a temperature control circuit, a counter circuit, and a microcontroller.
The MPPC is efficiently cooled down to -10 °C to reduce the dark count (approx. 1/20 that of the C10507 series). A USB port is also included to connect to a PC for threshold level setting and data acquisition. No external power supply is required since the circuitry is powered by the USB bus. The C11208 series extracts maximum performance from the MPPC to achieve excellent photon counting characteristics.
Three versions are available with either 1600, 400 and 100 pixels, corresponding to pixel sizes of 25 x 25µm, 50 x 50µm and 100 x 100µm respectively. A photon detection efficiency of up to 50% is possible with the largest pixel version.
