Avalanche Photodiodes

Innovative Components for Modern Optical Systems

Hundreds of components for industry and research

In today’s rapidly advancing technological landscape, optical sensors play a pivotal role across various industries, from telecommunications and healthcare to automotive and environmental monitoring. These sensors, which include diodes, photodiodes, and sensor arrays, and more are crucial for detecting and converting light into electrical signals, enabling a wide range of applications that are integral to modern life.

Optical sensors harness the unique properties of light to perform tasks that would be impossible or inefficient with traditional sensing technologies. Whether it’s the precise detection of light intensity, the accurate measurement of distance, or the monitoring of environmental conditions, these sensors provide the high sensitivity and fast response times needed for complex tasks.

Avalanche Photodiodes


We offer Excelitas Technologies Avalanche Photodiodes (APDs) on both Silicon (Si) and InGaAs materials.
* Si APDs cover the spectral range of 400 nm to 1100 nm
* InGaAs APDs cover 950 nm to 1550 nm.

An Avalanche Photodiode (APD) provides higher sensitivity than a standard photodiode and is for extreme low-level light (LLL) detection and photon counting.
