ABOUT THIS WEBINAR
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. Musgraves reviews 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.

***This presentation premiered during the 2021 Photonics Spectra Optics Conference. For information on upcoming Photonics Media events, see our event calendar here.

About the presenter
J. David MusgravesJ. David Musgraves, Ph.D., is director of research and development at Rochester Precision Optics LLC. He leads a team researching novel glass and plastic optics and the molding and coating of optical elements. Prior to this position, he served as president and CEO of IRradiance Glass Inc., where he oversaw production and manufacturing operations and the company's R&D efforts, funded through DARPA and AFRL (the Airforce Research Laboratory).

Formerly, Musgraves worked as a research assistant professor at Clemson University, studying infrared-transparent glasses. The group's research focused on the development and characterization of glasses for bulk, thin-film, and fiber applications. His individual research focuses on the integration of quantum computational modeling, optical spectroscopy, and thermal analysis to evaluate the evolution of amorphous structure across multiple length scales and to correlate this emergent structure with material properties.
