COOLING
As Figure 6 shows, the dark counts of the R3310-02 and
R4330-02 decreases by cooling the tube. Therefore, when
performing photon counting, it is recommended that the tube be
cooled down to about –20 . The cooler C2761 which features
temperature control from –30 to 0 is available from
HAMAMATSU.
