Abstract
Disclosed herein are embodiments of an illuminator for disinfecting a surface. The surface defines a first plane. The illuminator includes a line emitter configured to emit light in a continuous line along at least a portion of at least one edge of the surface. The light has a peak wavelength in a range of 100 nm to 400 nm. The illuminator also includes a curved reflector surface and an exit aperture defining a second plane transverse to the first plane. The line emitter is positioned between the curved reflector surface and the exit aperture, and the curved reflector surface is configured to redirect the light from the line emitter through the exit aperture across the surface.
