black light
Fluorescence-revealing illumination source
Black light is ultraviolet light invisible to the human eye that causes certain materials to fluoresce—to glow visibly.
Black lights are used to detect substances, authenticate documents, create visual effects at parties and haunted houses, and reveal what's hidden under normal lighting: The black light showed stains all over the carpet.
