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 HandbookInterferometry: Measuring with Light: Long applied to optical shop testing, interferometry is now used to measure many different types of parts in a variety of applications, such as optical system performance, surface roughness, surface form, and displacement of moving surfaces.An interferometer is an instrument that compares the position or surface structure of two objects. The basic two-beam division of amplitude interferometer components consists of a light source, a...Photonics HandbookMachine Vision Lighting: A First-Order Consideration: Lighting, sometimes a step-child in machine vision considerations, has become a first-order consideration in automated applications.In the beginning, automated inspection focused on the camera and optics, the algorithms, the interface hardware and the processor. Only rarely was attention paid to the lighting system or lighting...Photonics HandbookOptical Delay Lines: Key to Time-Resolved Measurements: To obtain an accurate means of creating reliable delays in any time-resolved spectroscopy or dynamic experiment, several factors about the delay line stage must be considered to reduce or eliminate errors associated with linear stages.One of the most critical elements of any time-resolved spectroscopy and dynamics experiment is the optical delay line. A typical optical delay line consists of a retroreflector or folding mirrors on...WHITEPAPERSPhotonics.com 1/14/2021Methods for Measuring Display Defects and Mura as Correlated to Human Visual PerceptionHuman vision and perception are the ultimate determinants of display quality, however human judgment is variable, making it difficult to define and apply quantitatively in research or production...Photonics.com 5/31/2019Tolerance Analysis Tools Take the Guesswork out of a Colorful Illumination Design ProblemTolerance analysis has largely been out of reach for illumination designers because of the time needed to perform the thousands of simulations required to get a meaningful statistical tolerance...Photonics.com 6/30/2020Health and Sanitization through UV LightingWith increased awareness and necessity for rapid disinfection methods due to the current coronavirus pandemic, ultraviolet disinfection has become a viable method to achieve it.
