FOCUS ON > Optics October 6, 2009 INDUSTRY NEWS Microvision commercially launches the first laser picoprojector Microvision (Redmond, WA) has commercially introduced the world's first laser-based picoprojector, called SHOW WX, which is based on the company's proprietary PicoP display-engine technology. SpaceX successfully tests DragonEye LIDAR on Space Shuttle SpaceX announced the successful demonstration of a proximity sensor or LIDAR sensor called DragonEye, launched aboard NASA's Space Shuttle Endeavour STS-127 mission on July 15th, 2009. Astronaut to keynote at Marketplace Seminar Former NASA astronaut Dr. Jeff Wisoff will give the keynote address at the 2010 Lasers and Photonics Marketplace Seminar in San Francisco, CA. Wisoff will discuss the National Ignition Facility (NIF) at LLNL. (BLOG) Stop killing optics! Photonics expert Sarah Diggs says she has "spent a lot of time praying to the gods of optics that I wouldn't destroy anything too valuable." Because technical training on how to clean optics is hard to come by, her blog provides important advice: first, stop cleaning!

Ophir-Spiricon's BeamGage, the next generation of laser beam analysis systems, is based on Ultracal, the company's baseline correction algorithm that helped establish the ISO standard for beam measurement accuracy. Includes innovative beam simulator, automatic camera control, custom algorithms.

TECHNOLOGY NEWS

New microphone technology is based on lasers At the 127th Audio Engineering Society Show, October 9-12, 2009 in New York City, Laser-Accurate microphone technology from Schwartz Engineering & Design (SED) will be introduced.

Hybrid solar cell promises higher efficiency RoseStreet Labs Energy, Inc. (RSLE; Phoenix, AZ) claims to have demonstrated the world's first nitride/silicon tandem solar cell.

QD Laser unveils miniature quantum-dot green laser QD Laser has developed, in collaboration with Professor Yasuhiko Arakawa of the University of Tokyo's Institute for Nano Quantum Information Electronics, the world's first green laser that uses quantum-dot semiconductor crystals.

Metamaterials are not required for "perfect" imaging A researcher at Scotland's University of St. Andrews has figured out that "perfect" imaging can be achieved with a lens made of ordinary materials, rather than metamaterials.

NEW PRODUCTS
	Compact large-stroke deformable mirror has low surface error Alpao expands its Hi-Speed DM Series with a new cost-effective DM37 that features all the unique performances of the Hi-Speed Series within a compact size (7.5mm): low surface error, large stroke (more than 35 µm), low nonlinearity errors (less than 3%), fast settling time (1 ms), and an excellent optical silver protected coating. Alpao; Biviers, France

FOCUS ON: Optics

Molded glass aspheres boost optical-design choices Precision glass molding of aspheric lenses allows a wide variety of optical designs with smaller size, reduced weight, and no post-polishing; these lenses can be made economically in medium to high production volumes.

Custom filters improve image quality of multiphoton microscopy In multiphoton microscopy, ultra-high-transmission filters with deep blocking and steep sides can effectively block all the excitation light while transmitting the precious fluorescence signal, greatly improving signal-to-noise ratio and imaging quality.

Plasma etching of micro-optics has its own rules Economies of scale result from producing many components on one wafer; however, differences in form factor, such as wafer material and thickness, require different approaches to processing.

Contact lenses have larger depth of focus A new type of contact lens corrects for farsightedness (hyperopia) or nearsightedness (myopia) just as ordinary contacts do, but does this with an extended depth of focus--about three diopters greater, in fact.
