Hamamatsu R3310-02 and R4330-02 are 51mm (2") diameter head-on type photomultiplier tubes having InGaAs (Cs) photocath-
odes, and linear focused CuBeO dynodes. The InGaAs (Cs) photocathode allows high sensitivity over a wide spectral range up to
1040nm.
The R3310-02 and the R4330-02 are selected for photon counting, and they feature low dark counts and excellent pulse height
distribution (PHD) of single photoelectrons.
