Hamamatsu Photonics has introduced their range of Silicon Photomultipliers (SiPMs); the S13720 series. Available in ceramic and surface mount package, these MPPCs have a structure to significantly enhance sensitivity in the NIR region, making them well suited for industrial LIDAR applications.

They feature higher Photon Detection Efficiency (PDE), increased from around 2% to approx. 7% at 905 nm. 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 (-40°C to 85°C and -40°C to 105°C respectively) making these devices well suited to many industrial applications.

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 1.1x10⁶, reduced crosstalk where crosstalk occurrences have been reduced to just six percent, while after pulsing affects are minimal. The typical dark count value is 500kcps.

The S13720 series is optimised for a variety of distance measurement applications, utilising light sources emitting in the near-infrared region. Example applications include LIDAR, distance measurement, flow cytometry, photon counting, high-energy particle detection and medical imaging.
