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 HandbookOptical System Design: Keeping the Coatings in Mind: The design of optical systems should balance the coating constraints with the optical and mechanical requirements. Understanding the key properties and limitations of optical coatings enables the system designer to improve the performance of the optical system.An optical coating engineer is frequently confronted with a difficult specification for a coating. Often the difficulty in the specification results from the particular form of the optical system.
