Camera Mimics an Insect's Compound Eyes
A hemispherical-shaped digital camera that mimics the design of ocular systems found in arthropods offers a wide-angle bug's-eye view and nearly infinite depth of field for applications ranging from advanced surveillance cameras to miniaturized endoscopes. "Full 180-degree fields of view with zero aberrations can only be accomplished with image sensors that adopt hemispherical layouts — much different than the planar CCD chips found in commercial cameras," said John A. Rogers of the University of Illinois at Urbana-Champaign. "When implemented with large arrays microlenses, each of which couples to an individual photodiode, this type of hemispherical design provides unmatched field of view and other powerful capabilities in imaging." |

IPG Photonics: Materials Processing Drives Sales Up 29%
The fiber laser maker reported a profit of $35 million, or 67 cents per share, for the first quarter of 2013. The total was up 17 percent from the same quarter a year ago, due largely to growth in materials processing, but fell short of analysts' expectations. |

‘Meta-Atoms’ Could Advance Optical Devices
Specially designed “meta-atoms” capable of stretching lightwaves and accelerating them to a speed faster than light could advance optical devices, a Missouri University of Science and Technology team theorizes. The work is the latest in a series of recent findings related to how light and matter interact at the atomic scale. |

Real-time Profiling for Focusing, M2, Divergence & Alignment
DataRay Inc.
Beam intensity profiling is an essential tool in many aspects of photonics. The precise intensity distribution in a focused laser beam is critical in many applications: flow cytometry, laser printing, medical lasers, and cutting lasers are just a few examples. Intensity profile measurements can characterize and improve a product or process, leading to substantial cost and time savings that can pay for the measurement instrument many times over. This white paper describes how the unique, patented, real-time multiple z-plane XYZTF capabilities of the BeamMap2 slit-scan profiler can speed and simplify laser assembly alignment.

FEATURED VIDEO
Princeton Instruments - IsoPlane SCT Spectrograph
Through its use of proprietary optics and a novel optomechanical design, the IsoPlane SCT (Schmidt-Czerny-Turner) improves upon the traditional Czerny-Turner-type spectrograph, which, despite being limited by the age-old design’s inherent image aberrations, is still the most commonly used research instrument in dispersive optical spectroscopy. Its novel optical design provides the ability to use the full spatial extent of their detector without loss of spectral or spatial resolution, and it provides the only major innovation to the design of research-grade imaging spectrographs in more than 20 years.
