Optics, Sensors & Detectors News
Cleaning Your Laser Optics Can Bolster Efficiency and Safety
Sep 8, 2017 — Laser optics, in use or in storage, always acquire a level of contamination from water, skin oils, dust and other substances. Contamination of this key component of a laser system can distort beam alignment and drift away a focused spot from the original setup. It also can negate the safety margins that were designed into the optics, resulting in optical damage under conditions where they would not normally occur. This is especially true for high-power laser systems, where contaminated
Optical Approach Finds Weak Spots in Jet Thermal Coating
EDINBURGH, Scotland, Aug. 29, 2017 — A strain-measurement technique uses optical analysis to reveal weak areas in the ceramic thermal barrier coatings that protect jet engine turbines from high temperatures and wear. This technique could be used to predict coating lifetime and could...
New Patterning Method Promises Easier Nanoscale Manufacturing
CHICAGO, Aug. 7, 2017 — A new method to precisely pattern nanomaterials could open a new path to manufacturing next generation electronic devices. Scientists at the University of Chicago and Argonne National Laboratory say their discovery could make building nanomaterials...
Optical Approach to Fracture Testing Measures Concrete Strength
