FEATURES
Super Compact: 13mm (1/2 inch) diameter
17mm seated length
High Sensitivity
Low Dark Current
SUPER COMPACT
PHOTOMULTIPLIER TUBES
R3810, R3811
APPLICATIONS
General Industrial Use
Exposuremeter for Microscope
Environmental Measurements
• Dust Counter
• Turbidimeter, etc.
Emission Spectroscopy
• Fluorescence Spectrophotometer, etc.
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 106.
They are optimal for applications where small detectors are required such a spectroscopy, biotechnology, medicine
and general industries.
