With conventional AR glasses, there is a trade-off in terms of quality and brightness between the external scene that a wearer actually sees and the contextual information that the wearer wants to visualize. Early solutions used multiple bulky optical components that were partially reflective and partially transmissive to mix the real-world and contextual scenes, with the result of a dimmed and distorted vision of both scenes. Though more recent AR head-mounted-display eyeglasses were patterned with diffractive gratings —with wavelength-size spacing that deflects contextual...Read full articleRelated content from Photonics MediaARTICLESAll-Optical Crystals Perform as Precision TimekeepersA team led by researchers at the University of California, Riverside (UC Riverside) has demonstrated time crystals that can persist indefinitely at room temperature, despite noise and energy loss....Photonics.com 2/24/2022Doping Process Increases Conductivity, Transparency of GrapheneAn interdisciplinary team of researchers from Columbia University and Sungkyungkwan University (South Korea) has introduced a clean technique to dope graphene via a charge-transfer layer made of...Photonics Spectra January 2022 IssueMachine-Readable Labels Identify and Track ObjectsA 3D-printing process developed at MIT creates barcodes and tags in the infrared spectrum to enable machines to track and identify objects.

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 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...Photonics HandbookThin-Film Coatings: A Buyers' Guide: The vast majority of optics used in precision scientific, industrial, biomedical, and military applications incorporate thin-film coatings on their surfaces. Therefore, it’s useful for almost anyone involved in the specification and purchase of optical components to have some familiarity with the typical performance characteristics, trade-offs and limitations of various coating types, as well as some knowledge of the capabilities of common thin-film production technologies. This article provides an objective overview of both these topics.What are thin-film coatings? The purpose of any optical thin-film coating is to modify the transmittance and reflectance properties of the substrate material to which they are applied. Most coatings...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).
