An HZB team has developed an ingenious precision rotary table at the EDDI beamline at BESSY II and combined it with particularly fast optics. This enabled them to document the formation of pores in grains of metal during foaming processes at 25 tomographic images per second - a world record.
Researchers at the National Institute of Standards and Technology (NIST) have used a laser detection and ranging (LADAR) system to image three-dimensional (3D) objects melting in flames. The method could offer a precise, safe and compact way to measure structures as they collapse in fires.
A team of UCLA electrical and computer engineers has created a physical artificial neural network — a device modeled on how the human brain works — that can analyze large volumes of data and identify objects at the actual speed of light. The device was created using a 3D printer at the UCLA Samueli School of Engineering.
What happens when really powerful magnets—capable of producing magnetic fields nearly two million times stronger than Earth’s—are applied to materials that have a “super” ability to conduct electricity when chilled by liquid nitrogen? A team of scientists set out to answer this question in one such superconductor made of the elements lanthanum, strontium, copper, and oxygen (LSCO).
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.

Many modern biological and biomedical research applications rely in part on fluorescence imaging to understand cellular structures and events. This application note details the techniques involved in fluorescence imaging, as well as possible imaging considerations, providing a point of reference for quantitating data obtained from images or movies.
Abrisa Technologies’ "Guide to Glass" provides information about the types of glass and their associated thermal, optical, chemical, mechanical, and electrical properties. This download also helps the reader better understand light and color; glare reduction; and glass strengthening methods using heat and chemicals.
The shutter in a camera system enables the control of the exposure time and thus, the level of signal in an image. The shutter also defines the quality of an image if the objects are moving, as well as setting the environment for experiments, especially involving synchronization with illumination light.
How design engineers for original equipment manufacturers (OEMs) of LiDAR systems can choose between differing sensor technologies.
Photron USA, Inc. of San Diego has launched a new versatile, high performance high-speed camera system. The FASTCAM NOVA brings together unique CMOS image sensor technologies and extensive high-speed digital imaging expertise that provide the camera with the flexibility to be used in a wide variety of applications. Available in three different models, the NOVA offers 12-bit image recording rates up to 12,800 frames per second (fps) at megapixel image resolution, and shutter speeds less than 300 nanoseconds. Recording rates to 1,000,000fps are available at reduced image resolutions. All of these things are available from a camera that is rugged, compact, lightweight and provides the best light sensitivity in its class.
MKS Instruments, Inc. (NASDAQ: MKSI), a global provider of technologies that enable advanced processes and improve productivity, has announced new additions to the Ophir® NanoScan™ 2s line of high power, scanning slit laser beam profilers. NanoScan products are NIST-calibrated profilers that instantly measure beam position and size with sub-micron precision for CW and kilohertz pulsed lasers. NanoScan profilers offer a choice of silicon, germanium, or pyroelectric detectors, which allows profiling lasers of any wavelength, from UV to far infrared, to 100μm and beyond.
LASER COMPONENTS can now provide custom ball lens profiles on the end faces of silica fibers. The plasma-based CMS process with ring-of-fire technology supports fiber diameters of 200, 365, 400, 550 and 600 μm, including other diameters within the limits of the equipment. For fibers used in medical applications, end-face processing can be carried out in a clean room in accordance with ISO 13485. The entire process is also compliant to ISO 13485 hygiene requirements.
