SensL announce the real alternative to photomultiplier tubes

10 March, 2009

(Cork, Ireland, and San Jose, CA; 10 March, 2009) SensL today announce a new website and
application focus around their Silicon Photomultiplier (SPM) technology, demonstrating real and
distinct advantages of this solid state alternative to the traditional photomultiplier tube (PMT).
‘Markets such as Homeland Security, Nuclear Medicine, and Analytical Instruments can
significantly benefit from the robustness, magnetic compatibility and improved form factor of the
SPM compared with older PMTs, while enjoying enhanced performance’, said Carl Jackson,
SensL’s CTO.

‘With a major PMT producer exiting the market, SensL are well positioned to add real value to our
customers, assisting them in moving away from old vacuum tube based technology and migrating
to a modern solid-state solution’, Jackson added.

Solid State, Silicon Photomultiplier (SPM) detectors are fast becoming the preferred choice for
applications such as High Energy Physics, Radiation Detection, PET/MRI, Confocal Microscopy,
Cytometry and Spectroscopy. In particular, the SPM has been shown to be a key technology
enabler in applications that reside in environments which are detrimental to the operation of
current PMT technology.

To coincide with the focus on the PMT replacement market, SensL today, launch the dedicated
website, www.siliconphotomultiplier.com which SensL will use to promote the technology and
educate the customer on the SPM as a replacement for the Photomultiplier Tube.
