MPPC characteristics vary with the operating voltage. The 25 μm pixel pitch type is suitable for applications requiring a wide dy-
namic range, because it has a large number of pixels and provides narrow-width output pulses. The 100 μm pixel pitch type is
suitable for applications where high gain is essential. Although increasing the operating voltage improves the photon detection
efficiency and time resolution, it also increases the dark count and crosstalk at the same time, so an optimum operating voltage
must be selected to match the application.
