A typical optical delay line consists of a retroreflector or folding mirrors on...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. 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 HandbookAcousto-Optic Devices: Charts showing the characteristics of acousto-optic scanning devices, acousto-optic figures of merit, and solutions for common problems with acousto-optic processor devices.ACOUSTO-OPTIC SCANNING DEVICES: CHARACTERISTICS MODULATORS Material Bandwidth (MHz) Rise Time (ns) Acousto Input Power (W) (Saturation) Material Wavelength Range...Photonics HandbookFlat Optics: Considerations When Buying: To simplify the process when purchasing flat optics, we will discuss the top six factors from a manufacturer’s perspective, all of which affect the three major areas of the purchasing decision: quality, delivery, and cost.Flat optics generally perform three main functions: They transmit light (windows), reflect light (mirrors), and fold light (prisms).
