The silicon photomultiplier, is also referred as a multi-pixel photon counter. The silicon photomultiplier is a radiation silicon sensor with single photon counting capability. Basically, it is based on reversed biased p/n diodes and is capable of detecting light from near ultra violet to near infrared. Furthermore, the silicon photomultiplier offers a highly attractive alternatives that combines the low-light detection capabilities state sensor. Apart from it, silicon photomultiplier has some of the features such as low-voltage operation, mechanical robustness, insensitivity to magnetic fields, and excellent uniformity of response. Moreover, silicon photomultiplier is used mostly in those applications wherever it is essential for low light radiation levels to be qualified and measured with high precision. The silicon photomultiplier signal output is an electrical current proportional to the number of photons hitting the sensor. Additionally, silicon photomultiplier has an advantages such as high gain (>1 x 106), low temperature dependency, very fast response, easy operation and short recovery time which can fuel the market of silicon photomultiplier.
