PHOTONIS is a world leader in photomultiplier tubes with a broad range of applications.

For over forty years, PHOTONIS has been the leading manufacturer of fast PMTs for the physics research community.
From 1956, when we introduced the world's first fast PMT until today, PHOTONIS has constantly set the standard in timing and linearity. Tubes such as the XP2020 are still the preferred choice in the most demanding time-of-flight (TOF) experiments, some twenty-five years after their introduction.
The excellent gain stability and high sensitivity of PHOTONIS' tubes, resulting from two decades of gamma camera tube experience, has made PHOTONIS' PMTs the preferred choice in many large physics calorimeters.

For detecting light from UV to visible wavelengths, the photomultiplier tube (PMT) is unequalled, thanks to:

• large sensing area
• ultra-fast response
• excellent energy resolution
• high gain
• low noise 

 PHOTONIS has its historic PMT roots in the 1950s, when the first big physics-research synchrotrons and detectors where being designed and built. Today, PHOTONIS offers a complete family of "fast" or "calorimeter" tubes, which are second-to-none.

And for fast tubes with high linearity, PHOTONIS is setting the standard in linearity performance

The PHOTONIS long experience in serving the gamma-camera PMT market feeds back into a wide range of very stable, high-sensitivity (and green-extended) bialkali PMTs: a perfect choice for traditional wavelength-shifted calorimeter readout.

For most physics research applications, PHOTONIS already has a standard PMT solution : view our range of product specifications. We also very often develop customised solutions for physicist's requirements.
