Detectors: Options for Low-Light Applications
SLAWOMIR PIATEK AND EARL HERGERT, HAMAMATSU CORPORATION
Developed in the early 1990s, the silicon photomultiplier (SiPM) is a solid-state photodetector whose sensitivity to light rivals that of a photomultiplier tube (PMT) in a regime where a few hundred...
Thin-Film Coatings: A Buyers' Guide
Trey Turner and Roger Kirschner, Research Electro-Optics Inc. (REO)
What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...
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...
Tunable Lasers: Generating Wavelengths from the UV Through the IR
Ian Read, MKS/Spectra-Physics
Applications facilitated by tunable lasers fall into two categories: situations in which one or more discrete wavelengths are not available from any single- or multiline fixed-wavelength laser, or...
Spectroscopy: 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...
Image Intensification: The Technology of Night Vision
Harry P. Montoro, ITT Night Vision
Image intensification, the basis of night vision, is a complex conversion of energy particles that occurs within a vacuum tube. An image-intensifier system works by collecting photons through an...
Adhesives for Fiber Optics Assembly: Making the Right Choice
Edward A.Y. Fisher, Henkel Corp.
Adhesives for fiber optic components that perform well on glass, metal, ceramic and most plastic substrates provide excellent chemical and solvent resistance. They also can act as an electrical...
Ultraviolet 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...
Photomultipliers: 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...
