PHOTOMULTlPLlER TUBES
R928, R955
Extended Red, High Sensitivity, Multialkali Photocathode
28mm (1-1/8 Inch) Diameter, 9-Stage, Side-On
FEATURES
Wide Spectral Response
R928 ........................................................ 185 to 900 nm
R955 ........................................................ 160 to 900 nm
High Cathode Sensitivity
Luminous ...................................................... 250 A/lm
Radiant at 400nm ............................................. 74mA/W
High Anode Sensitivity (at 1000V)
Luminous ........................................................ 2500A/lm
Radiant at 400nm ..................................... 7.4 105 A/W
Low Drift and Hysteresis
The R928 and R955 feature extremely high quantum efficiency,
high current amplification, good S/N ratio and wide spectral re-
sponse fromUV to near infrared. The R928 employs a UV glass
envelope and the R955 has a fused silica envelope for UV sen-
sitivity extension.
The R928 and R955 are well suited for use in broad-band spec-
trophotometers, atomic absorption spectrophotometers, emis-
sion spectrophotometers and other precision photometric in-
struments.
