ELECTRONICS: The new generation of mini laser bars from OSRAM Opto Semiconductors offers exceptional brilliance in the wavelength range from 910 to 1,020 nm. They are cost-effective, durable and can be easily adapted to meet the requirements of different applications thanks to their small size. In contrast to conventional fiber-coupled diode laser systems, the new bar structures allow more cost-effective beam-forming concepts to be used for fiber coupling. The associated reduction in system costs is a major factor in making diode laser systems more attractive for direct material processing - particularly in comparison with alternative laser solutions. Mini laser bars are available in various application-specific product families, with fill factors of 10 to 20 percent and typical efficiencies of up to 65 percent. In addition to pumping fiber lasers, the laser bars are also used for direct micro-material processing, such as marking and micro-welding.
The choice between helical and spur gears in gearboxes may seem straightforward. But with planetary gearboxes, however, the choice between helical and spur gears requires some additional thought. Here’s what you need to know to make the right choice.
Cas Smith is a biological engineer at Terrapin Bright Green, a consulting firm that specializes in green and sustainable design. At the core of his work is to explore how biomimicry can inform sustainable design. He discussed biomimicry and its implications for design and solving some of the world’s sustainability issues in an interview with Design News.
