METAL PACKAGE
PHOTOMULTIPLIER TUBE
R7400U SERIES
Compact size (16 mm diameter, 12 mm seated length),
Fast Time response (rise time 0.78 ns)
The R7400U series is a subminiature photomultiplier tube with a
16 mm diameter and 12 mm seated length. A precision engi-
neered 8-stage electron multiplier (composed of metal channel
dynodes) is incorporated in the TO-8 package to produce a noise
free gain of 700,000 times (R7400U). The R7400U series also
features excellent response time with a rise time of 0.78 ns. Vari-
ous types of the R7400U series are available with different spec-
tral response and gain ranges, including those selected specifi-
cally for photon counting applications. Hamamatsu also provides
a lens input option to the series (R7401 and R7402), effectively
doubling the active area.
FEATURES
Left: R7400U Right: R7401/R7402
World's smallest photomultiplier tubes assembled. (1/7th of the Hamamatsu R647)
The necessary components are built into a TO-8 package while retaining full photomultiplier tube performance to cre-
ate a new generation of photosensors.
Specially selected on account of low noise and high gain. For use in photon counting applications.
The lens window type doubles the effective input area to 12 mm in diameter.
