The wavelength range for PMT’s is from 150 nm to 900 nm, although the region between 850 nm to 900 nm is marginal. PMT’s are one of the most sensitive light detectors made. In many cases a PMT can detect a single photon (above).

    UV-A is the least harmful and most commonly found type of UV light, because it has the least energy. UV-A light is often called black light, and is used for its relative harmlessness and its ability to cause fluorescent materials to emit visible light - thus appearing to glow in the dark. Most phototherapy and tanning booths use UV-A lamps.
