Abstract (en)
[origin: WO9820365A1] An illumination and viewing system and method for detecting leaks by observing material (26) caused to fluoresce by being illuminated by a beam of ultraviolet light. The beam is concentrated by a parabolic reflector (10) coated to maximize ultraviolet reflection, and then passed through a filter (20) which reflects visible wavelengths while allowing transmission of ultraviolet and IR wavelengths. The fluorescing light is viewed through eyeglasses (24) which block wavelengths just below the wavelengths of the emitted fluorescing light.
