sensL has released what it claims is the industry's first four-sided, scalable, low-light detecting silicon photomultiplier array, the SPMArray. The device is intended for use in markets such as medical imaging, radiation detection, analytical instruments and high energy physics.

Solid-state silicon photomultiplier technology is replacing the vacuum tube-based photomultiplier tube, or PMT, in many miniature applications. Challenges have existed in creating large arrays of solid-state low light detectors due to the connections that were needed to the outside world. The four-side scalable low light detector solves the problems faced with scaling silicon photomultiplier technology to very large areas. This is a key requirement for the adoption of solid-state low light detector technology in many markets currently served by the PMT.

The small form factor makes the sensL SPMArray ideal for weight and space constrained hand-held radiation detection and identification systems, either for security applications or for simpler and more compact PET and SPECT ring assemblies in medical imaging applications. Additionally sensL has developed the packaging to allow adoption of the technology by customers who operate low light detectors in magnetic fields. The unique package used in the SPMArray is not impacted by large magnetic fields and is designed to be magnetic compatible up to 3 Tesla.

The SPMArray has been designed for high performance and flexibility and sensL offers the SPMArray with a full range of readout and evaluation boards designed to suit customer applications and rapid prototyping.
