What Is Photonics?
Photonics Media Editors
Photonics is the study of light and other types of radiant energy whose quantum unit is the photon. The impact of photonics on research, technology, navigation, culture, astronomy, forensics, and...
Nanopositioning: A Step Ahead
Scott Jordan, Brian Lula, and Stefan Vorndran, PI (Physik Instrumente) LP
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...
Lasers: Understanding the Basics
Coherent Inc.
Over 60 years have passed since the first demonstration of a laser in 1960. After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a problem,”...
Physical Constants & Conversion Factors
Physical Constants & Conversion Factors Length [I] 1 meter (m) = 39.3700 in. = 3.280833 ft = 1.093611 yd 1 kilometer (km) = 0.6213711 mi = 0.53996 nautical mi 1 micron (µm) =...
Diamond Machining: Ultraprecision Machine Technology
Engineering Staff, AMETEK Precitech, Inc.
Ultraprecision machining can be defined in general terms as the removal of material from a substrate utilizing a machine tool that operates at a resolution of 10 nm (0.4 μin.) or less. The...
Photonic Component Manufacturing: Moving Toward Automation
Bruce W. Hueners and Michael K. Formica, Palomar Technologies
Manufacturing the laser diode is complicated by the existence of multiple proprietary techniques and intellectual property barriers together with complex device physics and unique materials. ...
Positioning System Performance: Understanding the Rules
MKS/Newport
Abbe Error — Linear off-axis errors introduced by angular deviations coupled to a moment arm at the point of interest on stage mounted devices (θ in Figure 1). The effect of Abbe error...
Rules of Thumb
Photonics Rules of Thumb Scientists and engineers tend to want to answer simple relational questions with a blackboard covered with equations, even when questioners just want a rough estimate to...
Infrared System Design: Understanding the Process
William L. Wolfe, Professor Emeritus, University of Arizona, Optical Sciences Center
Infrared system design is not, like some circuit design, a synthetic process. One cannot start by stating the problem and proceeding in an orderly fashion to a final solution. Rather, we guess a...
Polygonal Laser Scanners: Fitting the Elements to the Task
Glenn E. Stutz, Lincoln Laser Co.
Reading and writing systems for polygonal scanners differ in the use of the scanner. However, many performance characteristics are similar for both. In writing applications, a light source, usually a...
Particle Image Velocimetry: Basics, Developments and Techniques
M. Kelnberger, InnoLas GmbH; G. Schwitzgebel, Universität Mainz
Particle image velocimetry (PIV) is an experimental tool in fluid mechanics and aerodynamics. The basic principle involves photographic recording of the motion of microscopic particles that follow...
