PMT Bases

We can manufacture PMT bases to your design or suggest one to match your needs.


* FET stabilized bases for high rate operation

* Tailored voltage division to improve linearity

* Compact assemblies

* Spring loaded assemblies

Below are a few examples


FET stabilized R1450 PMT base

Our stocked 2" PMT base and housing assembly is an improved direct replacement for CERN's 2" plastic PMT base.

Front end flange has the same mounting holes and O-ring groove as CERN’s base,
complete with μ-metal shield and FET stabilized spring loaded base.

Thicker housing plastic – no more cracked housings
Non-marring light guide clincher
Spring loaded base stays in one piece when removed
Higher noise immunity using coaxial cabling on signal lines

Modification of Hamamatsu H8500

Original H8500 with 64 pad readout (above) modified with a pixel to pixel gain flattening circuit and converted to an 8x8 X-Y readout while reducing the overall height by 5 mm (below).
