PHOTOMULTlPLlER TUBES

R4220

R4220P(For Photon Counting)

Very High Cathode Sensitivity with Low Noise Photocathode

FEATURES

Spectral Response ................................... 185 to 710 nm

High Cathode Sensitivity

Luminous ......................................................100 A/lm

Radiant at 410nm ............................................ 70 mA/W

High Anode Sensitivity (at 1000V)

Luminous ....................................................... 1200A/lm

Radiant at 410nm .....................................8.4 10⁵A/W

Low Dark Current .................................................... 0.2nA

Low Dark Counts (R4220P) ................................... 10 cps

Hamamatsu R4220 features extremely high cathode sen-

sitivity, high Gain, and low dark current.

Variant tube (R4220P) specially selected for photon

counting application is also available.

The R4220 is useful for fluorescence, chemilumines-

cence, Raman spectroscopy and low light level detec-

tion.
