Avalanche Photodiodes for Industrial and Analytical Applications
Excelitas' rear entry "reach-through" silicon APDs offer the best compromise in terms of cost and performance for applications requiring high speed and low noise photon detection from 400 nm up to 1100 nm. These APDs feature low noise, high quantum efficiency and high gain while maintaining reasonably low operating voltage. The active area varies from 0.5 mm to 3 mm to accommodate a large variety of applications including laser range finding, confocal microscopy, free space communication, fluorescence detection, DNA sequencing, and particle sizing.

The "S" series of the C30902 family of APDs can be used in either their normal linear mode (VR < VBR) or as photon counter in the Geiger mode (VR > VBR). This series is particularly well suited for ultra-sensitive photon measurements in biomedical and analytical instruments.
Precise temperature control can be achieved with a thermo electric cooler which can be used to improve noise and responsivity or to maintain constant responsivity over a wide range of ambient temperature.
High quantum efficiency can be achieved from 1100 nm to 1700 nm with our InGaAs Avalanche Photodiodes. They were designed to maintain high gain, high quantum efficiency and high bandwidth even with their large area of up to 200 µm. The short distance between to window and the active area allows easy interface with optical system.
