ARRAY4 4x4ポジションセンシティブSPM
SensL Array4 is a 4x4 matrix of silicon photomultipliers optimized for the readout of L(Y)SO, NaI:Tl
and CsI:Tl scintillators. Array4 is designed to serve as a low light photo detector in PET, X-ray and
radiation detection applications.
Integrated on a compact, non-magnetic package designed to have a minimal MRI footprint, Array4
can be tiled to build arbitrarily large, position sensitive detector systems. Low voltage operation, high
pixel uniformity, robustness and compactness make Array4 a cost effective and highly versatile
alternative for PIN, APD and small area multi-anode photo multiplier tubes.

Matrix9 12x12ポジションセンシティブSPMシステム
SensL Matrix9 is the first modular, turnkey readout system specifically designed for nuclear medical imaging applications. Building on SensL silicon photomultiplier technology, Matrix9 provides a fully solid-state, four-side scalable detector for the readout of L(Y)SO scintillator arrays. It integrates all the electronics required to localize, time stamp and discriminate scintillation events.
Digitized event data comprising time, location and energy are sent to the host system via high speed USB interface. Integrating multiple detector heads, Matrix9 can perform temporal coincidence analysis thereby reducing data rates to and computational load on the host system.
Matrix9 is available as a turnkey, fully integrated module or as an OEM sub-system for rapid integration.
SPMMatrix 256chポジションセンシティブSPMシステム
The SensL Matrix detector (SPMMatrix) is the largest area, highest channel count, Silicon Photomultiplier detector on the market today.
It consists of a 61.28mm x 61.28mm Silicon Photomultiplier detection area using SensL’s SPMArray4 detectors mounted onto a matrix board which provides bias to each array. Two analog boards each containing 16 analog channels provide amplification, discrimination and energy sampling. The SPMMatrix is also supplied with an FPGA board which implements cross-wire logic time stamping and readout/buffering events to the USB or openPET bus. It also contains SensL’s power board to provide the necessary bias to the arrays. The SPMMatrix is the ultimate large area SPM detection system on the market today and for easy portability, it is supplied in a handy travel briefcase.
SPMMicro 小型・低コストSPMセンサー
SensL’s SPMMicro series is a High Gain APD provided in a variety of miniature, easy to use, and low cost packages. The SPMMicro detector series is suitable for applications requiring high sensitivity, low noise detection in the visible to near IR range. The SPMMicro series is a solid-state detector sensitive to single photons. The detector consists of an array of Geiger Mode. Avalanche Photodiodes (APDs) or microcells, each individually coupled to integrated quench electronics. It is a type of detector referred to as a Silicon Photomultiplier (SPM). The SPMMicro combines high gain and quantum efficiency characteristics comparable to Photomultiplier Tube (PMT) detectors with the additional benefits of silicon technology such as compact size, magnetic field insensitivity, low operating voltage, robustness, and tolerance to overexposure.
Geiger Mode APDs have extremely high internal amplification that allows single photon sensitivity at room temperature.
The output of a Geiger Mode APD is an identical, fixed charge or current pulse for each single photon detected. By connecting an array of Geiger Mode APDs (microcell) in parallel, the summed output becomes proportional to the number of Geiger Mode pulses and hence proportional to the incident photon flux. SensL offers three detector sizes for the SPMMicro series: a circular 1mm diameter, square 3mm x 3mm active area, and a square 6mm x 6mm active area.
Each detector size is offered with a variety of microcell design sizes, 205m, 355m, 505m and 1005m.
SPMMini 冷却型SPMセンサー(PA内蔵)
The SPMMini is a solid state alternative to the Photomultiplier Tube(PMT). It combines the high gain (10E6) and high quantum efficiency of the PMT with the well appreciated benefits of silicon including size, low operating voltage, robustness, reliability, magnetic field insensitivity, tolerance of excess/ambient light, and suitability for miniaturization. In addition, the detector has high signal
to noise and fast timing properties.
The SensL SPMMini detector consists of a microcell array of Geiger mode Avalanche Photodiodes (APD), each individually coupled to integrated quench electronics, is known this is known as a Silicon Photomultiplier (SPM). The uniform high gain of the SPM allows the single photoelectron peaks to be clearly resolved permitting both single photon detection and measurement of the photon number.
The SensL SPMMini includes a transimpedance pre-amplifier, a Peltier cooler driver circuit to enable cooling to –20°C and integrated power supply as standard. A variety of add-on options to enhance functionality are provided, including C-mount (male) adapter and a fiber coupler (adapter and fiber cable included). The detector is mounted on a two-state Peltier cooler and housed
in a hermetically sealed TO8 can. During normal operation the SPMMini is cooled to –20°C. This allows greater performance over room temperature operation as the dark rate is reduced by over an order of magnitude. It is available with an active area of 1mm circular diameter or 3mm x 3mm (square) and with two different microcell sizes: 20μm and 35μm.
The features and applications for the SPMMini detectors are summarized below. Whether you are an OEM or a researcher,and your application is a portable instrument or a high tier laboratory analysis instrument, the SPMMini will provide significantbenefit over existing detector platforms.
