Characterization of Light Emitting Diodes (LEDs) and Compact Fluorescent Lamps (CFLs) by UV-Visible Spectrophotometry
Author: C. Mark Talbott, Ph.D., Robert H. Clifford, Ph.D.
Wednesday, October 10, 2012

The acceptance and commercial utilization of Compact Fluorescent Lamps (CFLs) and, more recently, Light Emitting Diodes (LEDs) have grown significantly in the past five years, leading to increased research. This paper demonstrates the use of a typical laboratory UV-Vis spectrophotometer to measure and characterize CFL and LED lamps, focusing on spectral characteristics such as peak wavelength, Full Width at Half Maximum, centroid wavelength, dominant wavelength, color, and color purity.

How to measure optical filter spectra accurately
Optical filters play an important role in enabling applications such as fluorescence microscopy and Raman spectroscopy. In these applications there are two distinct types of beams: the illumination (or excitation) beam and the signal (or emission) beam. Not only are these beams spectrally distinct, but also they differ significantly in their intensity – the signal beam can be a million times (or more) weaker than the illumination beam. Therefore, the ability of filters to selectively transmit...
