While the 20th was the century of film cameras, the 21st belongs to the digital camera.The digital camera represents an integration of optics, mechanics and electronics consisting of three layers (Figures 1a, b and c).

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 HandbookCamera Resolution: Combining Detector and Optics Performance: Most image-quality discussions center on resolution, which is thought to uniquely determine system performance. Resolution, however, is a more complex concept.Camera resolution depends upon the optical blur diameter and the detector size. Schade combined these to create an equivalent resolution that is a function of Fλ/d where F is the focal ratio,...Photonics HandbookAdaptive Optics: Taming Atmospheric Turbulence: For more than three centuries, the Earth’s atmosphere has frustrated astronomers. The layer of gases that we breathe also distorts the images formed by telescopes. This means that conventional telescopes of more than a few centimeters in diameter cannot reach the resolution limit set by their optics.To Isaac Newton the problem was clear, and in 1704 he realized the effects of atmospheric turbulence on image formation. Just as heat waves shimmering above a hot patch of ground can distort our...Photonics HandbookPHOTONICS BUYERS' GUIDE CATEGORIESSolar CoatingsNear-Field Scanning Optical MicroscopesA near-field scanning optical microscope is a scanning probe microscope that analyzes the surface of a specimen by recording the intensity of light as it is focused through a pipette and raster...Positioning EquipmentAdaptive OpticsAdaptive optics are optical components or assemblies whose performance is monitored and controlled so as to compensate for aberrations, static or dynamic perturbations such as thermal, mechanical and...COMPANIESII-VI Optical SystemsHIGH ENERGY LASER SOLUTIONS - II-VI Optical Systems provides collaborative support through all project phases, including consulting services at the project requirements definition phase, conceptual...Photonics Buyers' Guide
