Abstract
Although photon counting is an often encountered spectroscopic technique in the detection of low light levels, its use in undergraduate laboratories has been limited because of its cost. The circuit described in the article takes advantage of commercially available advanced Shottkey high speed counters. The board itself fits into a slot of a personal computer. The advantages in addition to the low cost, include the ability to program in high level languages and an easily expandable circuit which can control peripheral devices such as stepper motors.
