Since nanopositioning is a discipline that has enabled swiftly evolving application arenas as diverse as materials science, genomics, photonics, defense, biophysics and semiconductors, it’s unsurprising that its pace of innovation is nothing short of blistering in recent years.By its original definition, a nanopositioning device is a mechanism capable of repeatedly delivering motion in increments as small as one nanometer. Lately demands from industry and research have...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookCommon Infrared Optical Materials and Coatings: A Guide to Properties, Performance and Applications: The purpose of this guide is to identify the most common infrared-transmitting materials, pointing out key properties and their typical manufacturing and optical coating options.
