The 1P21 is a circular cage side-viewing photomultiplier designed for extremely low light applications. The tube has nine photomultiplier stages contained within a lime glass envelope mounted on a humidity-stable beige base. The RCA 1P21 outputs its maximum amplification at 380 nanometers. This tube is capable of detecting single photons, and will be destroyed if powered up while exposed to ambient light.
