Description
Description
Photodiodes bridge the gap between light and electronics. Many times precision applications such as CT scanners, blood analyzers, smoke detectors, position sensors, IR pyrometers and chromatographs utilize the basic transimpedance amplifier circuit that transforms light energy into a usable electrical voltage. In these circuits, photodiodes are used to capture the light energy and transform it to a small current. This current is proportional to the level of illumination from the light source. A preamplifier then converts the current (in amperes) from the photodiode sensor into a usable voltage level.
