RALEIGH, N.C., May 23, 2013 — An inexpensive material that can be “grown” in layers only one atom thick has yielded atomic-scale semiconductor thin films. The technique could be applied to make these devices wide enough to coat wafers that are 2 in. wide or larger. “This [method] could be used to scale...Read full articleRelated content from Photonics MediaARTICLESFiber Laser Welding Cuts Costs and Improves ResultsMost traditional — i.e., nonlaser — welding techniques currently in use are variations of arc welding.

The color of the emitted light depends on the semiconductor material and composition, with LEDs generally classified into three wavelengths: ultraviolet, visible and infrared.The wavelength range of commercially available LEDs with single-element output power of at least 5 mW is 360 to 950 nm. Each wavelength range is made from a specific semiconductor material family,...Photonics HandbookMachine Vision Lighting: A First-Order Consideration: Lighting, sometimes a step-child in machine vision considerations, has become a first-order consideration in automated applications.In the beginning, automated inspection focused on the camera and optics, the algorithms, the interface hardware and the processor.
