The photomultiplier provides extremely high sensitivity and ultra-fast response. Photomultiplier tubes (PMT) have high bandwidth and noise-free gain on the order of a million. This makes them ideal for the detection of extremely low light or short pulses of light. Photomultipliers can be used to detect photons from 115nm to 1700nm. A typical Photomultiplier consists of a photoemissive cathode (photocathode) followed by an electron multiplier and an electron collector (anode).
Hamamatsu offers the most complete range of head-on and side-on photomultiplier tubes from 3/8" to 20" in diameter.
