Super Compact, 13mm (1/2 Inch) Diameter, 9-stage, Side-on Type
R3810: Sb-Cs (185 to 650nm), R3811: Multialkali (185 to 850nm)
Recently, because of technology progress and requirements for cost reduction and high quality control, measurement
systems have been designed for smaller size and on-line operation.
Hamamatsu offers super-compact 13mm (1/2 inch) diameter side-on photomultiplier tubes with the seated length as
short as 17mm.
In spite of such compactness, these tubes have a 9-stage dynode that offers high gain in the order of 10
6
.
They are optimal for applications where small detectors are required such a spectroscopy, biotechnology, medicine
and general industries.
