Avalanche Photodiode Arrays
Avalanche photodiode arrays (APD arrays) are generally much smaller than multianode photomultiplier tubes but also have much less gain. APDs find applications in LIDAR, bioaerosol fluorescence detection, multispectral flow cytometry, confocal microscopy, and spectroscopy. They also have uses in high energy physics and particle position sensing. The list below features linear and two-dimensional (2D) APD arrays from Hamamatsu, First Sensor, Perkin Elmer, and Radiation Monitoring Devices (RMD). Available units range in size from 4 element 2 x 2 devices up to 64 element 8 x 8 devices.
