Photoluminescence Spectrometer (PRIORITY)

Edinburgh Instruments (Kirkton Campus, UK) introduces the FLS1000 state-of-the-art, modular photoluminescence spectrometer. The instrument excels in both steady state and time-resolved spectroscopy. It can be configured for spectral measurements from the ultraviolet to the mid-infrared spectral range, and for lifetime measurements spanning time resolutions over 12 orders of magnitude from picoseconds to seconds. Its ultimate sensitivity for the standard water Raman measurement is >30,000:1.

Robotic Vision Keeps an Assembly Plant at Home

A major manufacturer of electromechanical products had been operating six separate indexing assembly machines, each producing one of a family of more than 75 different products at about 40 parts per minute. The machines frequently sat idle as demand fluctuated for the various products. Labor expenses were high since each machine required a dedicated operator. The manufacturer considered moving the six machines and their entire production offshore to reduce labor expenses and save floor space at its European facility.

Wide-Area Surveillance Using HD LWIR Uncooled Sensors

The effectiveness of airborne search and rescue, navigation, and situational awareness tasks is predicated on the availability of high-resolution imagery that provides pilots with a clear picture and the widest possible field of view. While the human eye is extremely high resolution with an unmatched ability to detect high-spatial-frequency (HSF) objects across a wide field of regard, human vision can easily fatigue, is subject to environmental conditions, and is vastly degraded at night.

Snapshot High-resolution Hyperspectral Imaging

Traditional digital cameras are comprised of an image sensor, typically either a Charge-Coupled Device (CCD), or, more commonly Complementary Metal-Oxide Semiconductor (CMOS). In either case, these devices integrate an array of photodiodes which convert photons to current which is then integrated over time and digitized. The sensing device is agnostic to the wavelength of detected photons, as long as the energy of these photons is sufficient to create electron-hole pairs which can then be separated under an electric field.

Round Lens. Square Pixels. Accurate Images. Really?

Alens is cylindrical. It captures light in a circular plane for collection onto a rectangular digital sensor plane. This collection of photons is then transformed into electricity by smaller square pixels. Just how do these disparate shapes work together to provide usable images?

Selecting the Right Standard High-Voltage Power Supply

High-voltage power supplies drive a broad range of applications across diverse segments, including semiconductor, scientific, medical, industrial, and more. Designed to deliver stable supply voltages at 50 V and up, the power supplies, comprised of sophisticated components and specialized materials, must carefully manage the high voltages and associated effects, for example, corona and arcing. For systems developers choosing standard high-voltage power supplies, the specialized nature of high-voltage power calls for a power supply selection process that reflects the unique characteristics of the high- voltage power supply and its operation.

Ultra-Thin Camera Says Good-Bye to the Lens

A new proof-of-concept design retires one of the most familiar parts of a traditional camera: the lens. By swapping out the glass lens with a tiny array of light receivers, a California Institute of Technology team believes the thinner, lighter model supports a new wave of ubiquitous imaging.

DESIGNING A VISION SYSTEM: A Comprehensive Guide to the Technical Requirements for Building a Vision System for Your Unique Imaging Application

There are a number of factors that need to be considered when designing a vision system, including: the hardware platform, the operating system, the software and API, and the very things that make the vision system “see” – the camera and its lens. Although each aspect plays an important role in achieving desired results, the camera and lens are the essence of the vision system. As such, it is recommended that both the camera and the lens be selected as a pair based on overall system requirements. Here we discuss various elements of vision systems with a focus on the camera and lens.
