The latest generation p5-d series silicon photomultiplier tube has nearly 100% fill factor, photon capture efficiency (PDE) leading the same products in the industry and lower dark current rate. At the same time, through the optimization of lidar application scenarios, P5-d series silicon photomultiplier tubes can maintain low afterpulse probability and high temperature working range up to 105 ° C under high bias voltage, and fully meet the performance requirements of lidar customers for the receiving end.
