PHOTON COUNTING HEAD POWER
H7155, H7421, H7360, H8259
The C8855 is a counting unit with a USB interface and can be
GCompatible with USB interface (Ver. 1.1)
used as a photon counter when combined with a photon
counting head, etc.
GCompatible with Windows® 98/98SE/2000/Me
The counter of the C8855 has two counter circuits (double
counter method) capable of counting input signals with no dead
time. The USB interface easily connects to a notebook PC
GSample software supplied as standard item
GAccurate measurement with no dead time
allowing measurement in an even wider application field. When
used with a photon counting head, the C8855 supplies power
(+5 V / 200 mA) necessary to operate the photon counting head.
Since the C8855 is hot-swap compatible (plug and play
(double counter method)
GSupplies power to operate photon counting head
(power supply capacity: +5 V / 200 mA)
compatible), it helps you set up measurement environment
quickly. You can start measurement on the day the C8855 is
delivered by using the sample software that supplied with the
The C8855 cannot be used in simultaneous dual- channel measurements or long-time measurements with a fast time resolution. In
such applications, use the M8784 counting board also available from Hamamatsu.
• Time-resolved measurement (minimum resolution: 50 µs) for monitoring weak light detection like chemiluminescence
or biological clocks
• Quick measurement setups (hot-swap compatible)
You can start measurement by just connecting the USB cable without restarting the PC, if required software (device driver, etc) is
installed into your PC beforehand.
• Applicable to various measurement methods
The C8855 is fully controlled by DLL (dynamic link library) functions that supplied with the C8855.
User can create own software program, which is adequate for various type of user measurement, based on the DLL functions.
