Abstract: Multilayer optical film comprising at least a plurality of alternating first and second optical layers. Embodiments of the multilayer optical film are useful, for example, in UV-C shield, UV-C light collimator, and UV-C light concentrator applications.

Abstract: A light guide comprising a polymeric layer at least 25 percent transmissive over at least a 30 nm bandwidth in a wavelength range from 180 to 280 nm over a distance of at least 100 micrometers and visible light transparent reflecting layers (UV-C mirror) that are at least 50 percent reflective over at least 30 nm bandwidth in a wavelength range from 180 to 280 nm over an incident light angle of 0 to 90 degrees and that are at least 25 percent transmissive of visible light over at least 30 nm bandwidth in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees. The light guide is useful, for example, for antimicrobial surfaces.
