Silicon Photomultiplier with a Spectral Response Range from 300 to 800 nmSource: First Sensor AG
Using KETEK technology, First Sensor´s Silicon Photomultipliers are very precise state-of-the-art low level light detectors. They are suitable for many different applications like chemical analysis, medical diagnosis, scientific research and industrial measurement. Their peak sensitivity is at 420 nm to match with the LYSO scintillator emission peak in radiation detection applications. Besides the high photon detection efficiency the main features are low noise, large range of stable operation and an extremely low temperature coefficient of the gain.
The product line of silicon photomultipliers includes active area sizes from 1.2mm x 1.2mm up to 6mm x 6mm with various micro cell sizes. These detectors are available in compact THD and SMD packages. To reduce cross-talk between neighboring cells the silicon photomutipliers can be chosen with trench insulation between the micro cells. This reduces the photon detection efficiency slightly but improves the dark count rate significantly.
To ease integration into customer projects First sensor offers compact complete single photon counting modules with adjustable high stability voltage source, transimpedance amplifier, comparator with programmable reference and a USB-microcontroller. The module offers analog as well as digital output for maximum flexibility. In combination with a LYSO-scintillator on the silicon photomultiplier and a multichannel analyzer it is possible to measure nuclear radiation spectra, too.
