Avalanche Photodiodes & Large Area Avalanche Photodiodes

Lg. & Si APDs-96dpi

OSI Optoelectronics offers a series of avalanche photodiodes (APD) that are designed to make use of internal multiplication to achieve gain due to impact ionization. These high responsivity devices exhibit excellent sensitivity and fast response times.

The company also provides a patented product line of Large Area Avalanche Photodiodes (LAAPDs) from Advanced Photonix. These robust, lightweight devices feature a larger active detection area, higher quantum efficiency, greater linear response range, an improved signal-to-noise ratio, and are insensitive to magnetic fields. 

The APDs are available in several sizes of detectors with flat windows or ball lenses for optical fiber, high speed communications, bar code reader, optical remote control, laser range finder, medical equipment, optical fiber, and photometry applications. Additional features include low noise, low bias voltage, high bandwidths, and hermetically sealed TO-packages.
