PHOTOMULTIPLIER TUBE
R1464
High Anode Sensitivity at Low Supply Voltage
19mm (3/4 Inch) Diameter, 10 Stage, Head-On Type
185 to 850nm Response Multialkali Photocathode
The Hamamatsu R1464 is a 19mm (3/4") 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 R1464 exhibits a high anode sensitivity at relatively low supply voltage by virtue of improvement in secondary emitting
surface, compared with the Hamamatsu R663 photomultiplier tube which has the same spectral response characteristic and mechani-
cal specifications as the R1464.
