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 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. The information provided within this article is for reference purposes only.The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...Photonics HandbookDetectors: The Charge Injection Alternative: Charge-injection device (CID) technology provides a means to convert optical signals from 185 nm to 1100 nm to electronic charges that can be read out as a video signal or processed via computer. The CID imagers also are capable of directly (or indirectly) converting particle photons including electrons, ions, x-rays and other forms of ionizing radiation to measurable levels of electronic charge.Charged-injection device imagers are metal-oxide semiconductor (MOS) detectors that can be fabricated using PMOS, NMOS and CMOS integrated circuit technology, and may be configured as a...Photonics HandbookNSOM: Discovering New Worlds: Near-field scanning optical microscopy (NSOM) is an optical microscopy technique capable of imaging objects with a resolution below the diffraction limit of conventional (far-field) microscopy; i.e., below approximately half the wavelength of the light used.NSOM is suitable for studies on the mesoscopic scale (several tens to hundreds of molecular dimensions).
