Tunable Light Sources: A Popular Choice for Measurement Applications
VICKI LU and JOHN PARK, PhD, MKS/Newport
Many common spectroscopic measurements require the coordinated operation of a detection instrument and light source, as well as data acquisition and processing. Integration of individual components...
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...
Aspheric Lenses: Optimizing the Design
Jeremy Govier, Edmund Optics Inc.
With the understanding of aspheric lens manufacturing provided in part one of this article, designers have the tools to optimize their aspheres; the next step is to understand how to specify and...
Flat Optics: Considerations When Buying
Michael Naselaris, Sydor Optics Inc.
Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms). While most optical manufacturers make spherical and flat optics, a...
Optical Design Software: Fundamentals and Potential
Richard Pfisterer, Photon Engineering LLC
Optical design software allows the user to develop a configuration of optical elements that manipulate the trajectory of light for the purposes of creating an image, illuminating a target, coupling...
Greek Alphabet
Table of the Greek alphabet and what the letters are commonly used to designate. Name Capital Small Commonly Used to Designate Alpha A α Angles, coefficients, attenuation constant,...
Image Processing: Turning Digital Data into Useful Information
William Silver, Cognex Corp.
Images are produced by many means: cameras, x-ray machines, electron microscopes, radar and ultrasound. They are used in the entertainment, medical, scientific and business industries; for security...
Microassembly: Minimizing Error and Maximizing Precision
Bruce Fiala, Wright Industries
Progressive assembly operations such as guiding, gluing and bonding often take place around a static package in three-dimensional space. Integrating the different mechanical systems to ensure that...
Imaging Colorimetry: Accuracy in Display and Light Source Metrology
Ron Rykowski and Hubert Kostal, Radiant Imaging, Inc.
The market for flat panel displays (FPDs) has undergone tremendous growth, driven mostly by increased demand for televisions, cell phones, computers, digital cameras and MP3 players. Similarly,...
Radiometry: A Simplified Description of Light Measurement
Angelo V. Arecchi, Labsphere, Inc.
Radiometry involves several activities. The two most common are the description and measurement of optical radiation, and, starting with the knowledge of some aspects of optical radiation at one...
Digital Still Cameras: The Changing Face of Imaging
Morio Onoe, Professor Emeritus, University of Tokyo
The digital camera represents an integration of optics, mechanics and electronics consisting of three layers (Figures 1a, b and c). The top and the middle layers are printed circuit boards (PCBs),...
SWIR Imaging: An Industrial Processing Tool
Sensors Unlimited Inc., A Collins Aerospace company
Imaging has long been used in industrial processes to measure, monitor, control, or otherwise manage the production of goods. The challenge to the process designer is to develop a tool that captures...
Colorimetry: How to Measure Color Differences
Konica Minolta Sensing Americas Inc.
The use and importance of colorimetry has grown in unison with the increase of global manufacturing and processing. When plastic automotive trim produced on one continent must match a painted metal...
