Nearly 150 years ago, the physicist James Maxwell proposed that a circular lens that is thickest at its center, and that gradually thins out at its edges, should exhibit some fascinating optical behavior.
Fusion, the power that drives the sun and stars, produces massive amounts of energy. Scientists here on Earth seek to replicate this process, which merges light elements in the form of hot, charged plasma composed of free electrons and atomic nuclei, to create a virtually inexhaustible supply of power to generate electricity in what may be called a “star in a jar.”
It is not always easy to see if a switch is on or off! A new study shows that the same can be true of a molecular switch. This knowledge gives a new insight into the molecular switches, the GTPases, many of which have medical potential.
Yale University researchers have demonstrated one of the key steps in building the architecture for modular quantum computers: the “teleportation” of a quantum gate between two qubits, on demand.
Measuring very low power beams of light can be tricky; even small values of noise, drift or offset can have major impact on your readings. In this video, we’ll look at some best practices that can help you get the best performance from your very low power measurements.
Scanning slit profilers can make very accurate measurements of beam diameters as small as 5 microns, while cameras are limited to beams greater than 45 microns. This makes applications for focusing lasers or building optical systems much easier with a NanoScan. This video explains how to choose the right NanoScan for your application.
This video introduces First Sensor’s core competencies available from design concept to production.
FLIR thermal sensors can be used for the detection and classification of pedestrians in ADAS and self-driving cars, making them safer and less costly.
Zygo’s precision optics solutions such as high-quality mirrors, space-based lens assemblies, and other reconnaissance systems, have enabled high-performance solutions for defense and aerospace application.
For designers of medical diagnostic instruments, partnering with a reliable lighting expert can ensure the lighting system is optimized and generates homogeneous light that facilitates comparable and meaningful in vitro diagnostic analysis. Read more.

Predicting new trends in technology is not a simple task. The machine vision industry is no exception as new imaging technologies are constantly improving efficiencies, costs, and intelligence. In this white paper, Pleora Technologies offers some thoughts about the future trends in machine vision technologies.
Autonomous systems are not only in demand on the roads, they are also on the rise in the industry. Companies are particularly using drones for visual inspection and logistics. The artificial senses of First Sensor regulate navigation and interaction with humans.
Dr. Kent Rochford became SPIE’s new CEO earlier this summer, following the retirement of Dr. Eugene Arthurs, who stepped down in June. Recently, Dr. Rochford graciously made time to discuss his vision for SPIE initiatives already underway, as well as those the future may hold.
Common tools for non-contact temperature measurements include both thermal imaging cameras and spot pyrometers. Each works by detecting infrared radiation and translating it into temperature readings. Thermal cameras however, have several advantages compared to spot pyrometers, including image generation, temperature readings of each pixel of the entire image, and temperature readings from a longer distance.
Even tiny amounts of viruses can have disastrous consequences. RNA identification can reveal the type of virus present. A fast and sensitive technique based on optical detection has now been outlined in the journal Angewandte Chemie.
In research that may help bridge the divide between the nano and the macro, Brown University chemists have used pyramid-shaped nanoparticles to create what might be the most complex macroscale superstructure ever assembled.
Researchers have developed a light-based technique for measuring very weak magnetic fields, such as those produced when neurons fire in the brain.
The field of optical microscopy research has developed rapidly in recent years. Thanks to the invention of a technique called super-resolution fluorescence microscopy, it has recently become possible to view even the smaller parts of a living cell.
Quantum dots are nanometer-sized boxes that have attracted huge scientific interest for use in nanotechnology because their properties obey quantum mechanics and are requisites to develop advanced electronic and photonic devices.
