Hamamatsu R1527 features high cathode sensitivity, high cur-
rent amplification, and low dark current.
Variant tube (R1527P) specially selected for photon counting
application is also available.
The R1527 is useful for fluorescence, chemiluminescence,
Raman spectroscopy and low light level detection.
