What Is Photonics?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...
Selecting a Photodetector: Using WITS$ as a Rough GuideSelecting a Photodetector: Using WITS$ as a Rough Guide
Earl Hergert and Slawomir Piatek, Hamamatsu Corporation
Light is a versatile tool for investigating physical and chemical processes in nature. Any specific system being analyzed may, through the light it emits or reflects, communicate information about...
Lasers: Understanding the BasicsLasers: 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,”...
Excimer Optics: High Power Demands High ReliabilityExcimer Optics: High Power Demands High Reliability
Michael A. Case, Teledyne Princeton Instruments, Business Unit of Teledyne Technologies
The first high-reflectance mirror coatings for the UV and vacuum UV (VUV) were of the Al + MgF2 type produced in the late 1950s. Coatings of this design are still used today for multigas cavity...
Infrared Spectral Selection: It Begins with the DetectorInfrared Spectral Selection: It Begins with the Detector
Austin Richards, FLIR Systems, Commercial Vision Systems
Spectral selection is a powerful tool that enhances conventional imaging tremendously. Most imaging systems, including the human eye, are designed to image light over a broad range of the spectrum....
Spectroscopy: The Tools of the TradeSpectroscopy: The Tools of the Trade
Dr. John R. Gilchrist, Clyde HSI
All optical spectrometry techniques rely on the measurement of radiant power. The configuration of the instrument varies based on the measurement technique: absorption, emission, luminescence, or...
Ultraviolet Reflectance Imaging: ApplicationsUltraviolet Reflectance Imaging: Applications
Dr. Austin Richards, Oculus Photonics
Reflected-ultraviolet imaging is a rather mysterious area of the imaging field. There is relatively little actual UV imagery to be found on the Internet or in the literature compared to near-infrared...
Infrared System Design: Understanding the ProcessInfrared 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...
Photomultipliers: Low-Light, High-Speed SpecialistsPhotomultipliers: Low-Light, High-Speed Specialists
Ken Kaufmann, Hamamatsu Corporation
The applications where rapid detection of light is a must are many. They include a wide variety: semiconductor inspection, gene sequencing, oil well logging and high-energy physics. The reasons for...
Spectroscopy: Mastering the TechniquesSpectroscopy: Mastering the Techniques
Dr. John R. Gilchrist, Clyde HSI
The scope of optical spectroscopic instrumentation is indeed very broad. Many analytical methods rely on the interaction of radiation with matter and are often described in the context of quantum and...
