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 HandbookFiber Lasers: New Types and Features Expand Applications: Since its inception, the fiber laser has attracted users because of its large gain and the ability to produce continuous lasing. The quasi-continuous wave for industrial applications further broadens fiber lasers’ appeal.The modern fiber laser is pumped by high-power, multimode single-emitter diodes or diode bars, typically through a cladding surrounding a single-mode core. This single-mode core is typically 5 to 12...Photonics HandbookMicroscopy Illumination: Considering Nonlaser Light Sources: Metal halide and LED light sources are changing the illumination landscape in microscopy. Brighter, easier to use and growing in application, they are driving new options in fluorescence, conventional bright-field and other contrast techniques.As recently as five years ago, shopping for a microscope light source was fairly straightforward. For routine applications, it was tungsten halogen, typically 100 W, while for fluorescence, it was an...Photonics HandbookWHITEPAPERSDiode Lasers Enable Diverse Therapeutic ApplicationsDiode lasers have become the dominant laser type used in therapeutic applications.
