Thermoelectric Coolers
High Performance Thermoelectric Coolers C4877, C4878 Series
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 userfriendly functions such as easy temperature control and pilot lamp blanking. 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

Thermoelectric Coolers
Thermoelectric Coolers C659 Series
The C659 series is a thermoelectric cooler designed to reduce photomultiplier tube dark current and to enhance the photomultiplier tube lower detection limit. When used with a photomultiplier tube having an Ag-O-Cs photocathode 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, double pane window and custom socket assembly. The C659-50 series is designed for 38 mm (1-1/2") and 28 mm (1-1/8") diameter head-on photomultiplier tubes. The C659-70 series is specifically intended for use with 28 mm (1-1/8") diameter side-on photomultiplier tubes.
