Silicon photomultipliers have enhanced NIR sensitivity for LIDAR

April 04, 2017 // By Julien Happich
Hamamatsu Photonics' S13720 series of Silicon Photomultipliers (SiPMs) is available in ceramic and surface mount package and is designed with a new structure to significantly enhance sensitivity in the NIR region, for industrial LIDAR applications.

The series feature higher photon detection efficiency (PDE), increased from around 2% to approximately 7% at 905nm. This higher sensitivity enables longer range distance measurements or a better quality signal (SNR). In addition, they deliver a wide operating temperature and storage temperature range from -40 to +85ºC and -40 to +105ºC respectively). The S13720 series has a photosensitive area of 1.3x1.3mm, a 25μm pixel pitch and a fill factor of 47%. Other features include a high gain of 1.1x10 6, reduced crosstalk where crosstalk occurrences have been reduced to just 6%, while after pulsing affects are minimal. The typical dark count value is 500 kcps.
