Research led by ANU on the use of magnets to steer light has opened the door to new communications systems which could be smaller, cheaper and more agile than fibre optics.
A cover story appearing in the peer-reviewed journal Nanoscale Horizons reports a new bilayer material, with each layer measuring less than one nanometer in thickness, that someday could lead to more efficient and versatile light emission.
Quantum systems consisting of many particles are a major challenge for physicists, since their behaviour can be determined only with immense computational power. ETH physicists have now discovered an elegant way to simplify the problem.
Bristol Instruments’ model 771 is a high-resolution laser spectrum analyzer that measures the spectral characteristics of CW and high-repetition rate pulsed lasers that operate from 375 nm to 12 μm. Laser wavelength is measured to +/- 0.0001 nm and spectral resolution is as high as 2 GHz.
Iridian Spectral Technologies has designed and manufactured a wide range of dielectric optical filters for imaging and machine vision applications. Featuring steep edges, high transmission values, and high durability, these color filters can be used to improve contrasts, and isolate spectral regions and colors in images.

The recent introduction of 5-axis laser micro drill system expands the limits of micrometer range drilling. Canon’s unique technology creates flexible hole shapes and wider angles at significantly higher processing speeds. Stent production, injector hole drilling and micromachining will benefit.
A team of researchers at Purdue University’s Earth, Atmospheric, and Planetary Sciences Department recently tested the practicality of using shortwave infrared (SWIR) imaging for improving the detection of poorly-visible tornadoes in supercell thunderstorms. The team turned their attention to the Churchill Navigation ION digital recorder. The recorder’s ION and CameraLink adapter allowed the team to quickly connect and record video and metadata simultaneously from two different types of cameras; a SWIR camera provided by Sensors Unlimited and a visible-light camera.
A Modulation Transfer Function (MTF) is defined as a quantitative and objective measure of the quality of an image formed by a lens or and electro-optical system. This universally accepted measurement is appropriate for lenses of all qualities, and can also be calculated from lens design data which enables theoretical and actual performances to be compared. The MTF measurement has almost completely replaced older visual tests that relied on human judgement and provided very little information.
In many optical applications, the quality of the image formed by a lens is of critical importance. A high quality lens begins with a good design which is tolerant to small manufacturing errors. Next, the manufacturing process must be tightly controlled, from the individual lens elements to the final assembly. However, since small errors in manufacturing can result in serious loss of performance, end-of-line testing is then necessary to identify lenses that fail to meet the desired quality requirements. Therefore, there is a need for an objective and automated quality test to perform this task.
Sierra-Olympic Technologies recently introduced the affordable Viento-GT, an easy-to-use, thermographically-calibrated thermal camera. The Viento-GT is a highly reliable, high resolution and low-cost thermal imager that can deliver thermographically-calibrated digital data for every pixel. The camera is easy to power and control via a single Ethernet cable using the Gig-E Vision® and Power over Ethernet (PoE) standards.
