Diagnostics firm Hologic Inc. saw its revenues increase 2 percent to $625 million in its second fiscal quarter, powered largely by its 3-D mammography technology. Breast health revenues grew 8.5 percent to $238.7 million, while skeletal health revenues rose 4.7 percent to $23.5 million. The company attributed the increases to growing sales of bone densitometry and 3-D mammography systems. Partially offsetting these increases was an expected overall sales decline of 2-D systems. Meanwhile, diagnostics revenues fell 1.9 percent to $290.8 million and gynecological surgical revenues...Read full articleRelated content from Photonics MediaARTICLESLuminate NY Names Double Helix Top Winner of Competition's First RoundDouble Helix Optics was named the overall winner in the first round of the Luminate NY competition.

These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookFluorescence Lifetime Imaging: Choosing the Best Approach: Fluorescence lifetime imaging microscopy (FLIM), which measures the spatial distribution of the fluorescence decay, can be achieved either in the time or in the frequency domain. Each approach exhibits advantages and disadvantages, depending on the type of light detector and acquisition method employed.The term fluorescence is often applied as a synonym for photoluminescence, although luminescence actually covers fluorescence and phosphorescence. Both of these terms describe the process of...Photonics HandbookMachine Vision Cameras: Making the Right Selection: Improvements and affordability have broadened the use of vision systems for inspection, but several factors should be considered before making a purchase.Technological advances have resulted in new, higher-quality sensors that enable machine vision cameras to deliver greater features and functionality at a lower cost than ever before. These factors...Photonics HandbookImage Processing: Turning Digital Data into Useful Information: Digital imaging provides the means to enhance features of interest while attenuating details that are irrelevant to a given application, and then extracts useful information about the scene from the enhanced image.Images are produced by many means: cameras, x-ray machines, electron microscopes, radar and ultrasound.
