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 HandbookBeam Diagnostics: Meeting the Need for High Quality: Whether the application is scientific, commercial, industrial or medical, beam diagnostics has become an integral tool for users and manufacturers of lasers and laser-based systems. There is an increasing need to achieve, monitor and maintain higher quality beam characteristics to meet the demands of more sophisticated laser designs and tighter laser process tolerances.For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power,...Photonics HandbookDetectors: CCDs for Life-Science Applications: The CCD camera is becoming the imaging method of choice in biological laboratories for its resolution, versatility and ease of use. Choosing the best CCD for a given application, however, requires knowing how basic chip parameters affect performance.Since their invention in the late 1960s, charge-coupled devices, also called CCDs, have found widespread use in imaging applications.
