Hamamatsu Photonics K.K.’s Electron Tube Div.
a photomultiplier tube with enhanced UV sensitivity. The R11540 is a 28-mm-diameter
side-on device with a spectral response ranging from 185 to 760 nm. It produces
40% quantum efficiency at 350 nm and anode sensitivity of 11.3 x 105
A/W at 350
nm and 12 x 105
A/W at 420 nm. Its sensitivity and high gain of 1 x 107
make it suitable for low-light detection of UV and visible light in fluorescence
spectrometers. It also can be used as a fluorescence detector for high-performance
liquid chromatography, as a sulfur dioxide monitor, as a fluorescence immunoassay
detector for clinical use, and as a fluorescence, emission and atomic absorption
spectrophotometer. The photocathode material is Bialkali, the window material is
UV glass, and the wavelength of maximum response is 420 nm. Average anode current
is 0.1 mA, and operating temperature is from —30 to 50 °C. The instrument has
an 11-pin base and weighs 45 g.
