Frequently Asked Questions

An Avalanche Photodiode (APD) is a highly sensitive semiconductor device that operates in the reverse-biased mode to achieve internal multiplication of carriers.

APDs offer higher sensitivity, lower noise, and faster response compared to standard photodiodes. They are commonly used in low-light and high-speed applications.

APDs are available for various wavelength ranges, including UV, visible, and near-infrared (NIR). Make sure to select an APD that matches your desired wavelength.

Consider factors such as wavelength range, responsivity, dark current, gain, and operating voltage to select the appropriate APD for your specific application.

Yes, many suppliers offer custom configurations and arrays of APDs to meet specific requirements. Contact the suppliers directly to discuss your custom needs.

Did You know?

Avalanche photodiode (APD) finds its application in laser range finders, optical tomography, fiber optic communication systems, LIDAR, fluorescence detection, particle sizing and other photon counting situations. It has the advantage of high sensitivity and high response time. APDs are generally recommended for high bandwidth applications or where internal gain is needed to overcome high preamplifier noise. APDs are commercially available that span the wavelength range from 300nm to 1700nm. Silicon APDs can be used at wavelengths of 300nm-1100nm, Germanium: 800nm-1600nm, and InGaAs: 900nm-1700nm. Quantum efficiency, total leakage current and noise are important factors in choosing the right APD for your application.
