Comparison of tolerancing simulations and as-built optical performance in a precision optical system

Lorenzo Calvano, Paloma Matía-Hernando, Adnan Parwez, Thomas Siegel et autres

To properly account for imperfections in fabrication of lenses and mechanics as well as optics alignment limitations, it is necessary to run a tolerance analysis during the optical design process. But it is often unclear what level of detail the tolerance model …

Correlation Driven Transient Hole Dynamics Resolved in Space and Time in the Isopropanol Molecule

T. Barillot, O. Alexander, Bridgette Cooper, Taran Driver et autres

The possibility of suddenly ionized molecules undergoing extremely fast electron hole dynamics prior to significant structural change was first recognized more than 20 years ago and termed charge migration. The accurate probing of ultrafast electron hole dynamics requires measurements that have both …
