Hamamatsu Photonics introduced a new range of silicon photomultipliers in the form of the S13720 series. Available in ceramic and surface mount packages, these MPPCs (multi pixel photon counters) have a new structure to significantly enhance sensitivity in the near-infrared region, making them ideal for industrial LIDAR applications. They feature high photon detection efficiency, increased from around 2% to approximately 7% at 905 nm.
This higher sensitivity enables longer range distance measurements or a better quality signal. 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 ideally suited to many industrial applications.
The S13720 series has a photosensitive area of 1,3 x 1,3 mm, a 25 μm pixel pitch and a fill factor of 47%. Other features include a high gain of 1,1 x 106, reduced crosstalk where crosstalk occurrences have been reduced to just 6%, while after pulsing effects are minimal. The typical dark count value is 500 kcps.
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. For easy evaluation, a starter kit and evaluation module are available.
