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.

LIDAR Guns, Accuracy, and Speeding
Anyone who has driven a vehicle has encountered a Light Detection and Ranging (LIDAR) system in action. But how do you know if the detector is working? Let’s take a look behind the scenes at the beam, its scattered light, and the telescope that is used to collect data on the scattered light. The system then calculates the distance to the target and, subsequently, your speed.

Ultra-Narrowband Optical Bandpass Filters with Large Format and Improved Temperature Stability
Hard coated ultra-narrowband optical filters made using modern plasma processes offer much improved transmission, temperature stability and out of band blocking as compared to legacy soft coatings. These filters are used in optical systems as diverse as LIDAR (light detection and ranging), Doppler shift detection of plasma velocity, laser cleanup, chemical and gas sensing, as well as for cutting-edge astronomy and instrumentation applications.
