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 HandbookUnderstanding Surface Quality: A Practical Guide: Surface quality is one of the most scrutinized specifications in the optics industry. It is critical that the suppliers and customers have a consistent approach during the inspection process. These guidelines are intended to help ease communication between suppliers and customers for better products and business.Surface quality has become one of the most poorly understood specifications in the optics industry. A significant portion of the confusion stems from the two major competing (and largely...Photonics HandbookComponent Choices: Avoiding Tolerancing Mistakes: Designing an optical system involves more than simply understanding the theory behind optics. To design a system efficiently and economically, it is important to understand the capabilities of an optical shop and the interaction of the specifications involved in ordering and designing components.To the novice or casual user of optics, the acquisition of an optical system can be a very difficult experience. Failure to understand the ground rules can result in unnecessarily high cost, late...Photonics HandbookCleaning Optics: Choosing the Best Method: Cleaning optical elements improves performance, providing proper materials, techniques and handling procedures are used to minimize the risk of damage.Optics can be contaminated in many ways.
