Presentation: “Intelligent Material Design for Infrared Optics”
Presented by: J. David Musgraves, Rochester Precision Optics LLC
Chalcogenide glasses offer an opportunity to expand the possibilities available to infrared optical designers by providing the ability to create IR optical materials with specifically designed refractive index dispersion. The ability to create a material with a known dispersion profile allows optical engineers to design achromatic and apochromatic lenses in the infrared — and could also enable creation of Risley prism systems with minimized primary and secondary dispersions.
The flexibility to design the dispersion profile is available in chalcogenide glasses, as opposed to crystalline IR materials, because the compositions can be tuned through the inclusion of additional ingredients — analogous to what is done in visible optics systems. In his session, Musgraves, director of research and development at Rochester Precision Optics LLC, will review recent work in creating and characterizing suites of chalcogenide glasses, with an aim toward developing tight composition/property dependence relationships that can allow the prediction of glass compositions with dispersion profiles designed for specific optical applications.
Musgraves’ presentation will be available starting at 10:15 a.m. EDT on April 28.
Additional sessions will include the keynote, “From the Design Lab to the Factory Floor: How Optics Manufacturers Move Swiftly from Concept to Creation,” from Ulrike Fuchs, vice president of strategy and innovation at asphericon; an optics market analysis on the effects of COVID-19, from Tom Hausken, senior industry adviser at The Optical Society (OSA); and “Optical Coatings: A Full Spectrum of Solutions,” from Dan Fiore, vice president of North American Coating Laboratories (NACL).
The two-day Photonics Spectra Optics Conference runs April 27-28. Registration is free for the event, which is offered exclusively online.
