TEHVPMT Cooled Photomultiplier Assemblies
A thermoelectrically cooled photomultiplier assembly combines high voltage, a shielded detector housing and a selectable side-window tube for weak optical signals.

Best suited to
Scanning fluorescence, transmission, reflection and source-emission measurements.
Selecting a configuration
Select the tube and output electronics for the wavelength and signal level. Tube model names identify internal components; the product listed here is the integrated cooled assembly.
