PHOTOMULTlPLlER TUBES

InGaAs (Cs) Photocathode, Wide Spectral Response, 51mm (2) Dia., Head-on Type For Photon Counting : Low Dark Counts, Excellent P.H.D.

Hamamatsu R3310-02 and R4330-02 are 51mm (2) diameter head-on type photomultiplier tubes having InGaAs (Cs) photocathodes, 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.
