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...
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...
Transparent Ceramics: Enabling Large, Durable, Multifunctional Optics
Mohan Ramisetty, Lee Goldman, Nagendra Nag, Sreeram Balasubramanian and Suri Sastri, Surmet Corp.
Single-crystal sapphire has been the material of choice for defense and other applications that require extremely durable optics, but aluminum oxynitride (ALON) and magnesium aluminate (spinel) have...
Detectors: Guideposts on the Road to Selection
Earl Hergert, Hamamatsu Corporation
Any number of medical, industrial, and analytical applications requires the detection of light. Chemiluminescence, bioluminescence, fluorescence, and atomic absorption are just a few, and all require...
Common Infrared Optical Materials and Coatings: A Guide to Properties, Performance, and Applications
Jeffrey L. Tosi and Kumar M. Khajurivala, Janos Technology LLC
The optical materials selected for an optical system depend upon the application, the required system performance and the environment in which the system is to perform; thus the materials’...
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...
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...
Mirrors: Coating Choice Makes a Difference
JDSU
The basic difference between the household mirror and the optical mirror is that one is coated on the back surface and the other is coated on the front. For optical applications, a front-surface...
Beam Diagnostics: Meeting the Need for High Quality
Coherent, Inc.
For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power,...
