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.

The Measurement of High Optical Densities (up to 8 Abs) in the Near-Infrared
The optical densities of various materials used in the manufacture of laser safety eyewear have been determined in the NIR. The lens materials were measured over wavelength ranges corresponding to the laser wavelengths for which the eyewear was designed (InGaAs, 980 nm and Nd:YAG, 1064 nm). Prior to measurement, a variety of filters of known optical density were used to validate the photometric performance of the spectrophotometer. Using the addition of filters technique, photometric range,...
