Diffraction Gratings: Selection Guidelines
David Ventola, Optometrics Corp., an Omega Optical Holdings company
Diffraction gratings are optical components with a periodic structure that separate light into beams traveling in predictable directions based on their wavelength. The grating acts as the dispersive...
Superresolution Microscopy: An Imaging Revolution
Marie Freebody, Contributing Editor
Superresolution optical microscopy, for which the Nobel Prize was awarded to Eric Betzig, Stefan Hell, and William Moerner in 2014, has been one of the most momentous developments in the life...
Polarization-Based Imaging: Basics and Benefits
XING-FEI HE, TELEDYNE DALSA
There are three fundamental properties of light: intensity, wavelength, and polarization. Almost all cameras today are designed for monochrome or color imaging. A monochrome camera is used to measure...
QCL Primer: History, Characteristics, Applications
Hamamatsu Corporation
Since its first successful operation in 1960 at Hughes Research Labs, the laser technology has been at the center of innovation and research. Semiconductor lasers first made their appearance in 1962...
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...
Measuring Small-Beam MFD: Overcoming the Challenges
DERRICK PETERMAN, PhD, MKS Ophir
Profiling beams under 10 µm in size is one of the more challenging beam profiling applications. There are numerous reasons for this, including the very small size. Focal plane arrays commonly...
Lasers for Microscopy: Major Trends
Marco Arrigoni, Nigel Gallaher, Darryl McCoy, Volker Pfeufer, Matthias Schulze, and Daniel Callen, Coherent Inc.
Laser development for the microscopy market continues to be driven by key trends in applications, which currently include superresolution techniques, multiphoton applications in optogenetics and...
Passive Athermalization: Maintaining Optical Performance Over Temperature
Janos Engineering, Janos Technology LLC
For rotationally symmetric optical systems, either the lens or the detector moves along the optical axis to maintain optical performance. If the compensating axial motion is accomplished without the...
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...
Lens Aberrations: Avoiding Defects in Imagery
Bruce H. Walker, Walker Associates
A lens collects light from a point on an object and focuses it to a corresponding conjugate point on an image. Under most conditions, the lens fails at this task because of some error in the...
Rules of Thumb
Photonics Rules of Thumb Scientists and engineers tend to want to answer simple relational questions with a blackboard covered with equations, even when questioners just want a rough estimate to...
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...
Laser Perforation: The Diffractive Beamsplitter Advantage
Moshe Bril, Holo/Or Ltd.
The basic setup in laser perforation includes a pulsed laser, a lens and either a moving mirror, a rotating web or both. Each laser pulse creates a hole in the material. During the blank time in...
Global Optimization: A Tool for Successful Design
Thomas G. Kuper and Thomas I. Harris, Optical Research Associates
Some efforts in global optimization research for optical design center around probabilistic methods such as global search. While promising for small problems with few variables, these methods...
Optical Objective Systems: A Schematic Guide
Warren J. Smith, Rockwell Collins Optronics
Simple Meniscus Lens The simple meniscus lens is almost universally used in inexpensive cameras. To get an image of good quality it must be used with a separate aperture stop, reducing the...
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,...
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...
Adaptive Optics: Taming Atmospheric Turbulence
Tom Gonsiorowski, Adaptive Optics Associates, Inc., a Wholly Owned Subsidiary of Northrop Grumman Systems
To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...
