Abstract
An apparatus and method which detects temperature variations of an LED used with spectroscopic devices. The apparatus and method uses a source to supply a signal to the LED. A detector coupled to the LED detects a signal at the LED. A controller is coupled to the detector to determine variations in operating characteristics of the LED resulting from changes in temperature.
