Single Photon Counting with a focus On Biomedical Applications

Introduction: Over the past few years a growing number of companies have come to rely on Photon Counting for applications that range from particle sizing, atmospheric studies and advanced forms of biomedical research. Photon counting technology using Avalanche Photodiodes are achieving 70% photon detection efficiencies with sub nanosecond timing jitters and low dark counts (typically < 250cps). Besides being extremely small and rugged, these photon counting devices based on avalanche photodiodes have rapid recovery from overload, wide dynamic range and very low afterpulsing probabilities.
