Paper Abstract

The performance of an LED-based, dual-beam, spectrophotometer is discussed. The difficulty with producing an LED based instrument in the past has been the limited choice of LEDs, particularly in the blue/green region. Recent advances in LED technology have made such a device possible. The instrument discussed uses commercially available LEDs and other off-the-shelf electronic components which result in a low cost durable device. A mathematical model of the device is constructed, and the sources of deviations from this model are discussed.
