R1463P

PHOTOMULTIPLIER TUBES R1463, R1463P High Anode Sensitivity at Low Supply Voltage, 13mm (1/2 Inch) Diameter, 10 Stage, Head-On Type, Multialkali Photocathode, (185nm to 850nm) 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 importance. 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.
