High-speed, compact Si APD that does not require temperature adjustment


The S15415 series is a gain-stabilized APD (GS APD) with a built-in temperature compensation function inside the sensor. This realizes constant gain without the need for temperature adjustment. It is suitable for laser monitors of optical rangefinders used in a wide range of applications, from consumer to industrial.
