Use a soft dry cloth to wipe clean the surface of the MPPC module. · Since the window of this product is made with soft resin, don’t push nor touch the window surface by the hard or tip object. If the window needs to be cleaned, use ethyl alcohol and wipe off the window gently. · For instructions on how to install the sample software to your PC, refer to the “Quick start guide” that comes with the MPPC module. When installing the sample software, make sure that the MPPC module is not connected to the PC. Otherwise, the software installation might fail. · Power to this product is supplied from the USB port on the PC. Due to the USB specifications, the maximum power that can be supplied from one USB port is limited to 5 V, 500 mA. Avoid connecting two or more units to one USB port through a hub. Typical power consumption of the MPPC module is 200 mA. · Depending on the PC model, the power supplied from the USB port might be interrupted when the power saving function or screensaver is activated. In this case, the MPPC module also stops operation and might create problems when the PC returns from power saving or screensaver mode. If USB power from your PC is interrupted in this same way, disable the power saving function and screensaver. For information on PC functions and settings, refer to the PC operation manual. 7 MPPC modules C10507-11 series, C10751 series Options Fiber adapter A10524 series The A10524 series fiber adapters are designed to couple the MPPC module to an optical fiber. Two types are available for FC and SMA connectors. Using this adapter allows efficiently coupling the MPPC module to a GI-50/125 multi-mode fiber. This adapter screws on for easy attachment. Note: Optical fiber is needed separately. Suitable MPPC module: C10507-11-025U C10507-11-050U C10507-11-100U A10524-01 (FC type) A10524-02 (SMA type) Coaxial converter adapter A10613 series The A10613 series is a coaxial adapter that converts the SMB coaxial connector for signal-output on the MPPC module to a BNC or SMA coaxial connector. This adapter allows connecting a BNC or SMA cable to the MPPC module. A10613-01 (SMB-BNC) A10613-02 (SMB-SMA) Description of terms Analog output voltage The MPPC module analog output is set so as to obtain a peak voltage of 100 mV at 1 p.e. Dark count Output pulses are produced not only by photon-generated carriers but also by thermally-generated dark current carriers. The dark current pulses are measured as dark count which then causes detection errors. The dark count can be reduced by lowering the temperature. In the MPPC module, the count value measured at 0.5 p.e. is defined as the dark count. Photon detection efficiency: PDE This is a measure of what percent of the incident photons were detected. Not all carriers generated by the incidence of photons will create pulses at an amplitude large enough to be detected, so photon detection efficiency is lower than quantum efficiency. In the MPPC module, the count value measured using a threshold of 0.5 p.e. is defined as the dark count. p.e. (photon equivalent) This indicates that one photon was detected. For example, a 1 p.e. pulse is equivalent to the pulse (including noise components) obtained when one photon is detected. 8 MPPC modules C10507-11 series, C10751 series Lineup of MPPC module Internal MPPC Type no.
