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...
Measuring Aspheres: Selecting the Best Technique
Amy Frantz, Edmund Optics Inc.
The benefits of aspheric lenses are numerous: They allow for a reduction in spherical aberrations and are ideal for focusing or collimating light, as they can achieve a low ƒ-number. Aspheres...
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...
Aspheric Lenses: Design Considerations
Jeremy Govier, Edmund Optics Inc.
Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...
Interferometry: Measuring with Light
Zygo Corporation
An interferometer is an instrument that compares the position or surface structure of two objects. The basic two-beam division of amplitude interferometer components consists of a light source, a...
Broadband Spectrophotometry: A Fast, Simple, Accurate Tool
Iris Bloomer, n&k Technology, Inc.; Rebecca Mirsky, Al Shugart International
Designing devices that incorporate ultrathin films is an important means of enhancing yields. However, characterizing ultrathin films provides a challenge for mainstream metrology tools such as...
Dynamic Interferometry: Getting Rid of the Jitters
John Hayes and James Millerd, 4D Technology Corporation
Conditions on the factory floor and in industrial cleanrooms with high-capacity air filtration systems can hamper the use of interferometry. Another problem is the testing of large-aperture mirrors...
Semiconductor Lasers: An Overview of Commercial Devices
JDSU
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...
Polarization Mode Dispersion: Concepts and Measurement
Paul Hernday, Fiber Optic Measurement Training and Consulting
There are three fundamentally different dispersive phenomena in optical fiber, of which polarization mode dispersion (PMD) is the most complex. In digital multimode fiber systems, a light pulse...
