Sensing in the shortwave infrared (SWIR) range (wavelengths from 0.9 to 1.7 microns) has been made practical by the development of Indium Gallium Arsenide (InGaAs) sensors. Sensors Unlimited, Inc., part of UTC Aerospace Systems, is the pioneer in this technology and clear leader in advancing the capability of SWIR sensors. Founded in 1991 to create lattice-matched InGaAs structures, Sensors Unlimited...

QPSI™ Technology Shrugs Off Vibration from Common Sources When image stabilization became available on digital cameras, it vastly reduced the number of photos ruined by camera shake. The new technology eliminated the effects of common hand tremors, greatly improving image quality in many photo situations. Animated comparison of a PSI measurement with fringe print-through due to vibration, and the same...

DynaPhase® Dynamic Acquisition for Extreme Environments Confidence in metrology, no matter the conditions Fizeau Interferometry has become a trusted standard for precise metrology of optical components and systems. Traditionally, these instruments were required to be installed in lab environments, where conditions were carefully controlled, to ensure high precision measurements were not compromised. However, today a growing number of applications demand...

FFT Spectrum Analysers, such as the SRS SR760, SR770, SR780 and SR785, take a time varying input signal, like you would see on an oscilloscope trace, and compute its frequency spectrum. Fourier's theorem states that any waveform in the time domain can be represented by the weighted sum of sines and cosines.The FFT spectrum analyser samples the input signal, computes...

The nano mechanical imaging (NMI) mode is an extension of the contact mode. The static force acting on the cantilever is used to produce a topography image of the sample. Simultaneously, at each pixel force curves are produced and used to extract quantitative material properties data such as adhesion, deformation, dissipation...

We are pleased to announce that we are now delivering an on-board image compression video camera, which is able to transmit high-quality images and reduce the data output in real-time. Baumer is supplementing the hugely popular LX series with 2, 4 and 25 megapixel cameras with integrated JPEG image compression and frame rates of up to 140 fps. With the...

Electronic products can emit unwanted electromagnetic radiation, or electromagnetic interference (EMI). Regulatory agencies create standards that define the allowable limits of EMI over specific frequency ranges. Testing designs and products for compliance to these standards can be difficult and expensive, but there are tools and techniques that can help to minimise the cost of testing and help to enable designs...

The future belongs to LED technology. The long lifetime and high energy efficiency of these devices form the main reason for changing over to this technology for illumination requirements in Machine Vision. Depending on what the requirements are in terms of price, performance and flexibility, the user can find the best solution in the market using this state-of-the-art technology. The...

Investing in a new scanning electron microscope (SEM) is a strategic move towards enhancing business performance and operational efficiency. Whether you're grappling with the sluggishness of traditional floor models or the prolonged turnaround times of external services, upgrading to a more accessible, faster, and easier-to-operate SEM is essential. Desktop SEMs: Cost-Effective Solutions The decision between a desktop SEM and a...

We are pleased to announce the OP415 Polarity Analyser from OptoTest - the latest innovation in polarity testing solutions. This polarity tester was designed to test 24-fibre MTP/MPO cable assemblies efficiently, but is easily configured to test for 8-fibre and 12-fibre cables. It is pre-loaded with 12-fibre and 24-fibre polarity types A, B, and C plus the ability to create and...
