The Hamamatsu R1463 is a 13mm (1/2") diameter, head-on type photomultiplier tube having a multialkali photocathode designed for
use in UV to near IR spectrophotometers and other analysis equipments where wide range response and high gain are of impor-
tance. The R1463 exhibits a high anode sensitivity at relatively low supply voltage by virtue of improvement in secondary emitting
surface. The R1463P is for photon counting with low dark counts. It has an HA coating with a magnetic shield for decreasing glass
scintillations.
