SPMMini

The SPMMini is the first solid state alternative to the long established Photomultiplier Tube (PMT). It combines the high gain and 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.

SPMMini: High performance high gain silicon photomultiplier_front and backThe SPMMini includes transimpedance preamplification, a Peltier cooler driver circuit to enable cooling to  -20C 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 die is mounted on a Peltier cooler and housed in a hermetically sealed TO8 can. During normal operation the SPMMini is cooled to -20C. This allows even greater performance over room temperature operation as the dark rate is reduced by over an order of magnitude. It is available with a circular active area of 1mm circular diameter or 3mmx3mm. A variety of microcell sizes are offered to allow the SPMMini to optimize dynamic range and detection efficiency.
