A PMT is similar to a phototube in that it has a photoelectric cathode that absorbs light and emits an electron. Most often a photocathode is semi-transparent and usually consists of a thin layer of evaporated Cs, Sb, and K atoms (or a mixture of all three). Hamamatsu R928 The envelope of the photomultiplier is typically quartz; only wavelengths that can be tranmitted through the window to the photocathode can be detected. Environmental Measurement. Introduction Light detection technolgy is a powerful tool that provides deeper understanding of more sophisticated phenomena. Chemiluminescence, bioluminescence, fluorescence, and atomic absorption are just a few, and all require a detector to convert the light into an electrical signal. Brand new | Business.
