The C4877 series and C4878 series are thermoelectric coolers constructed
with enhanced electrostatic and magnetic shielding (C4877 Series). This
minimizes the influence of external noise on the photomultiplier tube and
thus significantly improves photometric accuracy. These coolers offer user-
friendly functions such as easy temperature control and pilot lamp blank-
ing. The C4877 series is designed for use with 51 mm (2") or 38 mm
(1-1/2") diameter head-on photomultiplier tubes, and the C4878 series for

The C659 series is a thermoelectric cooler designed to reduce photomultipli-
er tube dark current and to enhance the photomultiplier tube lower detection
limit. When used with a photomultiplier tube having an Ag-O-Cs photoca-
thode in DC mode, the dark current can be reduced to 1/200 of its normal
level at room temperature.
In cooling a photomultiplier tube one sometimes encounters problems such
as dewing on the incident window and leakage current on the socket or base
of the tube. But these problems are eliminated by use of an evacuated, dou-
ble pane window and custom socket assembly.
The C659-50 series is designed for 38 mm (1-1/2") and 28 mm (1-1/8") di-
ameter head-on photomultiplier tubes. The C659-70 series is specifically in-
tended for use with 28 mm (1-1/8") diameter side-on photomultiplier tubes.
