Focusing Beam Intensity with Top Hat Beam Shapers
A top hat output beam has a uniform, focused intensity distribution with a well-defined shape and size, as well as sharp edges. This article explains how to obtain such an illumination profile with a laser beam. Introduction to top hat output A top hat output from an optical system including a laser beam describes the … Continue reading
LEDMOTIVE Dynamic Daylight System Lights Repsol Oil Refinery
LEDMOTIVE Technologies S.L has installed its patented system of intelligent spectral playback in one of the Repsol industrial complexes, a 24/7 control room in the control room of an olefin plant located in Tarragona Spain. The aim of this new lighting system is to provide the dynamism of daylight. The system reproduces the changing illumination … Continue reading
Dynamics of a Light Pulse Interacting with Nanosized Objects
Unveiling the spatial and temporal dynamics of a light pulse interacting with nanosized objects opens new ground for understanding nanoscale phenomena. Here, researchers resolve the time-dependent behavior of a single germanium plasmonic antenna in the mid-infrared by measuring the complex optical field response in amplitude and phase with sub-optical-cycle precision, with the promise to extend the observation … Continue reading
View the Clouds of Camelopardalis
Terry Hancock shared a photograph of the “Clouds of Camelopardalis,” which was taken at Grand Mesa Observatory in Purdy Mesa, Colorado in the United States, using Chroma Technology‘s LRGB filters. This photo was taken over 2 days, with a total acquisition time of 5 hours. Chroma manufactures the highest quality astronomy filters with durable, sputtered … Continue reading
Producing µ-Precise Fine Tubes and Stents
PHAROS or CARBIDE femtosecond lasers from Light Conversion are the most common choice for the production of µ-precise fine tubes and stents. It is possible to process both metallic and bioresorbable stents using lasers that are equipped with a harmonics module. Moreover, femtosecond lasers eliminate costly post-processing and cleaning steps. Ultrashort laser systems are the solution for industries such as medical technology or micro-optics. To watch a … Continue reading
