Photon counting

The PCEdu-1 photon Counting Fundamentals package is an entry-level lecture and laboratory tutorial on low-light sensing or semiconductor device physics and is suitable for OEM or academic environments. Available from !%SensL Technologies Ltd.%!, the module contains tools and documentation that will take users from the basic theory of photon counting and photodetection to application examples. Lecture notes in a series of six modules cover topics such as quenching fundamentals, and photodiode operation and characterization, in preparation for five laboratory sessions that will enable trainees to gain experience with related devices. A miniature photon counter, a passive quench circuit, a calibrateed reference detector, filters and optical attenuators, and other items are provided for performing the experiments.
