Advanced Photonix, a division of OSI Optoelectronics, introduced compact and rugged Large Area Avalanche Photodiodes (LAAPDs). The new LAAPDs are available in various sizes, from 3 mm, 5 mm, 10 mm, to 16 mm active area diameters. The devices operate at up to 2000 volts with gains of up to 300. With extremely low noise levels and high stable gain, the photodiodes are offered in cooled or uncooled packages.
The large area avalanche photodiodes are available with high sensitivity in Blue, Red, or Deep UV spectral regions down to 150 nm with 120% quantum efficiency. They are ideal for scintillation or direct X-ray detection applications.
