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 HandbookSemiconductor Lasers: An Overview of Commercial Devices: Within only a few decades, the semiconductor laser diode has evolved into a family of robust, reliable devices, with individual conversion efficiencies of better than 60 percent, continuous output powers of several kilowatts, modulation rates of several tens of gigahertz, and wavelengths from 0.4 to beyond 2 µm. This article discusses the structures and characteristics of the most common commercial varieties.Laser diodes vary widely in their wavelengths, powers, spectra and beam quality. Yet they share two fundamental components with all other lasers: an optical amplifier and a resonator that confines...Photonics HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size.
