About This Webinar
High-precision lenses and mirrors for short wavelength light, including deep-UV (DUV) and x-ray, are manufactured by fully utilizing both traditional polishing techniques, which require empirical knowledge through trial and error, and modern polishing and surface-measurement techniques.

Kume provides an overview of techniques and innovations in manufacturing high-precision optical surfaces (unique-shape lenses, CaF2 lenses, x-ray mirrors, etc.).

Additionally, he showcases recent approaches to overcome technical challenges related to surface quality to fabricate ultrahigh-precision optical surfaces for short-wavelength light.

***This presentation premiered during the 2023 Photonics Spectra Conference. For more information on Photonics Media conferences, visit events.photonics.com.
