SiPM Product Selection Guide

Compared to other photosensor technologies, such as PiN diodes, APDs and PMTs, SiPMs offer a winning combination of properties. These include high gain, excellent PDE and fast timing along with the practical advantages associated with solid-state technology: compactness, ruggedness, low bias voltage and insensitivity to magnetic fields. This page is intended to help the user navigate our catalog of sensors.

SensL is now recognized as a market leader for low-light sensing products as a result of 10 years continuous product improvements, serving hundreds of customers. The SensL advantage lies in a number of fundamental factors that come together to result in a product and service that surpass the competition.

Silicon Family

SensL have three different silicon series, each of which which combines high photon detection efficiency (PDE) with low dark count rate, but with other varying characteristics that are suited to specific applications. The different silicon series can be summarized as follows:

  • C-Series – General purpose, blue sensitive, lowest cross-talk and noise.
  • J-Series – Blue sensitive, highest PDE, optimized for fast timing applications, high-fill factor package.
  • R-Series – General purpose red sensitive, highest PDE, optimized for fast timing applications.

The full datasheets for each silicon series are found on the individual product pages. The table below summarizes some of the main characteristics for each silicon series, based on a 35um microcell.
