Three-Axis Gimbal Mount

The high precision, AU300-XZ Motorized Three-axis Gimbal Mount from Optimal Engineering Systems, Inc. (OES) (Van Nuys, CA) features full 360O rotation of each axis. The rigid black anodized aluminum alloy frame handles loads to 10kg (22.5 lbs) and has the clearance (300 mm x 300 mm, 11.8 in. x 11.8 in.) necessary for mounting lasers, cameras, optics, etc. The Azimuth stage rotary table has a compact 214 mm x 214 mm (8.425 in. x 8.425 in.) foot print. Each axis features: Low backlash worm gear drives and precision "V" grove & cross roller bearings for very high resolution of 3.6 arc seconds, and repeatability and positional accuracy to 18 arc seconds. Travel speed of each axis is 10O per second. To learn more, click here

Researchers Film Droplets Getting Blown Up by X-ray Laser

This illustration shows how an ultrabright X-ray laser pulse (orange beam) vaporizes part of a liquid jet (blue), creating umbrella-shaped films of liquid and sending shock waves through the jet (bright stripes at top and bottom). (SLAC National Accelerator Laboratory) Researchers have made the first microscopic movies of liquids getting vaporized by the world’s brightest X-ray laser at the Department of Energy’s SLAC National Accelerator Laboratory. The new data could lead to better and novel experiments at X-ray lasers, whose extremely bright, fast flashes of light take atomic-level snapshots of some of nature’s speediest processes.

Engineers Set New World Record in Solar Cell Efficiency

A diagram of the spectrum-splitting, four-junction mini-module developed at UNSW. (Courtesy of UNSW) A new solar cell configuration developed by engineers at the University of New South Wales has pushed sunlight-to-electricity conversion efficiency to 34.5% – establishing a new world record for unfocused sunlight and nudging closer to the theoretical limits for such a device. The record was set by Dr Mark Keevers and Professor Martin Green, Senior Research Fellow and Director, respectively, of UNSW’s Australian Centre for Advanced Photovoltaics, using a 28-cm2 four-junction mini-module – embedded in a prism – that extracts the maximum energy from sunlight. It does this by splitting the incoming rays into four bands, using a hybrid four-junction receiver to squeeze even more electricity from each beam of sunlight.

Optics Breakthrough Could Revamp Night Vision

By etching grooves in the film, the light is redirected and almost all of it is absorbed. The absorbing layer is less than 1/2000th the thickness of a human hair. (Credit: Dr. Thomas P. White, Australian National University) A breakthrough by an Australian collaboration of researchers could make infrared technology easy-to-use and cheap, potentially saving millions of dollars in defense and other areas using sensing devices, and boosting applications of technology to a host of new areas, such as agriculture. Infra-red devices are used for improved vision through fog and for night vision and for observations not possible with visible light; high-quality detectors cost approximately $100,000 (including the device at the University of Sydney) and some require cooling to -200°C.

Advanced Passive Thermal Management Technologies for Power Electronics: Solutions to Reduce Noise, Power Consumption, and Operating Costs

Components housed within power electronic devices continue to shrink in size and increase in power. This trend results in high heat flux components integrated into small packages; driving the need for enhanced thermal management to ensure high performance and long life for the devices. Properly managing the thermal loads within these systems can be challenging; and traditional solutions of larger pumps and fans result in more noise and higher power consumption.
