1. A light guide comprising
(A) a polymeric layer at least 25 percent transmissive over at least 30 nm bandwidth in a wavelength range from 180 to 280 nanometers over at least a distance of 100 micrometers and
(B) a plurality of visible light transparent UV-C reflecting layers that is
(i) at least 50 percent reflective over at least 30 nanometers in a wavelength range from 180 to 280 nanometers over an incident light angle of 0 to 90 degrees and (ii) at least 25 percent transmissive of visible light over at least 30 nm in a wavelength range of 400 to 800 nm over an incident light angle of 0 to 90 degrees,
wherein each visible light transparent UV-C reflecting layer is a dielectric mirror comprising a first optical layer and an adjacent second optical layer.
