There are nearly 500 types and sizes of tubes in the standard range of EMI photomultipliers, with diameters ranging from 30ram to 300mm, not including 'specials' to meet individual customers' requirements.

These tubes are supplied with a wide variety of cathodes and, as the typical response curves for 30mm and 50mm photomuttipliers indicate, they provide an extensive spectral coverage.
