Asphere Measurement System

The AspheroCheck UP from TRIOPTICS (Weden, Germany) is designed with a completely automated measurement process that requires no manual interaction to accurately measure aspheres. Lenses with aspherical surfaces are frequently used in small, light, high-performance optics to reduce spherical aberration. While the decentration of an aspherical surface can be determined with the centration measurement that is also used for spherical lenses, determining a possible tilt requires an additional, off-axial test.

World’s Brightest Laser Sparks New Behavior in Light

Physicists from the University of Nebraska-Lincoln are seeing an everyday phenomenon in a new light. By focusing laser light to a brightness 1 billion times greater than the surface of the sun — the brightest light ever produced on Earth — the physicists have observed changes in a vision-enabling interaction between light and matter. Those changes yielded unique X-ray pulses with the potential to generate extremely high-resolution imagery useful for medical, engineering, scientific and security purposes.

New Class of ‘Soft’ Semiconductors Could Transform HD Displays

A new type of semiconductor may be coming to a high-definition display near you. Scientists at the Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that a class of semiconductor called halide perovskites can emit multiple, bright colors from a single nanowire at resolutions as small as 500 nanometers. The findings represent a clear challenge to quantum dot displays that rely upon traditional semiconductor nanocrystals to emit light. It could also influence the development of new applications in optoelectronics, photovoltaics, nanoscopic lasers, and ultrasensitive photodetectors, among others.

'Magic' Alloy Could Spur Next Generation of Solar Cells

In what could be a major step forward for a new generation of solar cells called "concentrator photovoltaics," University of Michigan researchers have developed a new semiconductor alloy that can capture the near-infrared light located on the leading edge of the visible light spectrum. Easier to manufacture and at least 25 percent less costly than previous formulations, it's believed to be the world's most cost-effective material that can capture near-infrared light—and is compatible with the gallium arsenide semiconductors often used in concentrator photovoltaics.

Will the smart grid become a reality?

Today’s lead INSIDER story featured a new building block for the smart grid: a solid-state transformer."

The SST is a fundamental building block in the smart-grid concept," said NC State Distinguished Professor Iqbal Husain. "It can scale down voltage for use in homes and businesses, but it can also scale up voltage from solar panels or other residential-scale renewable sources in order to feed that power back into the grid."

What do you think? Will the smart grid become a reality?

Lindley Johnson, Planetary Defense Officer, NASA Headquarters, Washington, D. C.

NASA’s Planetary Defense Coordination Office (PDCO), managed at NASA Headquarters in Washington, D.C., is responsible for early detection of potentially hazardous objects, like asteroids and comets, and issuing warnings about their potential impacts. This requires teamwork from observatories around the world. NASA’s Planetary Defense Officer, Lindley Johnson leads the global effort to detect and follow near-earth objects

New Heater Technology Reduces Space, Weight and Failure

The SmartHeat SLT Thin-Film heater is a new and unique self-limiting heater solution. Minco’s SmartHeat regulates temperature at the molecular level, eliminating the need for separate sensors and controllers which minimizes points of failure and reduces the total system footprint for space and weight sensitive applications.

Direction Finding: Its Importance in Our Changing World

Direction finding is important for civilian, defense, and law enforcement purposes. It involves the use of specialized instruments, antennas, and methods to determine the physical location of a source of RF energy or target. A radio direction finder estimates the direction of an emitter by measuring and evaluating electromagnetic field parameters. This 10-minute audio-visual presentation looks at direction-finding methods, applications, configurations, and benefits. Viewers will be able to submit questions and download a new Rohde & Schwarz white paper that is an essential resource for understanding all aspects of direction finding.

Product of the Month: July 2017

Tektronix, Beaverton, OR, introduced the TTR500 Series USB vector network analyzer, a USB-based RF test instrument. It includes VectorVu-PC analysis software and built-in bias tee for testing active devices. The 2-port, 2-path S-parameter VNA features 100 kHz to 6 GHz frequency range, 122 dB dynamic range, less than 0.008 dB trace noise, and -50 to +7 dBm output power. The built-in bias tee allows for 0 to ± 24V, and 0 to 200 mA on both ports for active devices. The analyzer operates with any Windows PC or laptop, and VectorVu-PC software controls and calibrates the instrument. For automated test systems in design or manufacturing, the software offers programmatic support for SCPI commands, including command compatibility with common legacy VNAs for integration into existing test systems. In addition, the software offers an offline mode for data analysis with an output file format compatible with common EDA simulation tools. Accessories include a rugged carrying case, rack mount kits, phase-stable cables, attenuators, adapters, and calibration kits.
