Briefs: Photonics/Optics
Researchers at MIT and several other institutions have developed a method for making photonic devices — similar to electronic devices but based on light rather than electricity —...
Articles: Photonics/Optics
Two basic components make up the value added to a work piece by the micro-electric discharge machining (μEDM) process: form and surface finish....
Articles: Photonics/Optics
Four lasers can be used for micro welding: pulsed neodymium-doped yttrium aluminum garnet (Nd:YAG), continuous wave (CW) fiber, quasi continuous wave (QCW) fiber, and nanosecond fiber. Each laser type...
News: Imaging
For years many engineers have assumed that you cannot encode more than one holographic image in a single surface — at least without losing resolution. Caltech researchers made the idea a reality.

Laser Confocal Scanning Microscope
The new Olympus (Waltham, MA) LEXT® OLS5000 3D laser confocal scanning microscope delivers precise imaging in a fast, easy-to-use system for research and development and quality control...
INSIDER: Photonics/Optics
Physicists at the University of California, Riverside have developed a photodetector by combining two distinct inorganic materials and producing quantum mechanical...
INSIDER: Communications
Scientists have taken an important step towards using ‘twisted’ light as a form of wireless, high-capacity data transmission which could make fiber optics...
INSIDER: Imaging
A silicon solar cell harvests the energy of the sun as light travels down through light-absorbent silicon. To reduce weight and cost, solar cells are thin, and while silicon absorbs...
Q&A: Photonics/Optics
Learn about a new laser-based method for 3D printing of large metal objects called Diode-Based Additive Manufacturing (DiAM).
Briefs: Photonics/Optics
A team of researchers have designed, built, and tested two devices, called superconducting undulators, which could make X-ray free-electron lasers (FELs) more powerful,...
Articles: Materials
The challenges in achieving greater accuracy in optical thin-film coatings, both historically and in today's coating processes, are many and deserve our scrutiny. The...
Application Briefs: Photonics/Optics
To shrink device size yet still tightly control performance, new technology often requires increasingly stringent surface specifications. Characterization tools, in turn, must keep pace by...
Articles: Photonics/Optics
Area array and line scan cameras are each suited for unique machine vision applications. Area array cameras, for all intents and purposes, are “conventional” cameras that use sensors with two-dimensional pixel arrays. The...
News: Semiconductors & ICs
Researchers at the National Institute of Standards and Technology (NIST) have for the first time examined, with nanometer-scale precision, the variations in chemical composition and...
Application Briefs: Photonics/Optics
Introduced in 2010, CoaXPress (CXP) has become a leading standard for high-end machine vision, as well as life sciences, security, and defense applications. The CXP standard...
Briefs: Photonics/Optics
Optical coherence tomography (OCT) is a scanning technology commonly used by ophthalmologists to check for eye diseases. A team of scientists has figured out how to retrofit these high-performance machines with...
Briefs: Photonics/Optics
Ionic liquids—salts made by combining positively charged molecules (cations) and negatively charged molecules (anions) that are liquid at...
Briefs: Photonics/Optics
How fast is an electron? Australian scientists were able to measure it. Australia's fastest camera, located at the Attosecond Science Facility, has revealed the time it takes for molecules to break apart. The...

High-Energy UV lamp
McPherson, Inc. (Chelmsford, MA) introduces the flow-controlled windowless, hollow cathode UV lamp Model 629. This broad-spectrum source emits ionized gas emission lines with little or no absorption by neutral...
INSIDER: Photonics/Optics
In the galaxy NGC 4993, located approximately 130 million light-years from Earth, two neutron stars collided. And, for the first time, scientists detected the...

Fiber-Optic Environmental Radiation Dosimeter
An all-optical, fiber-optic-coupled remote radiation sensor was developed using luminescent, copper-doped quartz material. The key to the technology is the doped quartz material, which produces a luminescence signal that is directly proportional to the radiation dose.
Briefs: Photonics/Optics
The scanning tunneling microscope (STM) has become one of the most powerful tools used in studying the surface structure of electrically conducting solid-state materials at an atomic...

Compact, Lightweight, Athermal, Nanocomposite Telescopes with Freeform Optics
Small space missions such as CubeSats frequently require telescopes with highly sophisticated optical systems that are also low in mass and cost. The very limited spacecraft volume and mass limits also preclude adjustments to maintain critical alignment with change in...
INSIDER: Motion Control
The James Webb Space Telescope will be the most powerful space telescope ever built. With a 21-foot diameter, the telescope’s primary mirror is six times larger than the one used...
INSIDER Product: Imaging
Fiber Optic Cables
OFS (Norcross, GA) has expanded its AccuRibbon® DC Fiber Optic Cable product family to include fiber counts up to 864. Currently, AccuRibbon DC cables are offered in fiber counts up to 432. Super-absorbent...
INSIDER: Semiconductors & ICs
In today’s increasingly powerful electronics, tiny materials are a must as manufacturers seek to increase performance without adding bulk. Smaller also is better for...
INSIDER: Imaging
Los Alamos National Laboratory has produced the first known material capable of single-photon emission at room temperature and at telecommunications wavelengths. These carbon...
INSIDER: Photonics/Optics
