Abstract
An inspection system for ascertaining the surface of a glass sheet that contacted the molten metal bath during production of the glass by the float process and thus has traces of fluorescent metal or metal oxides thereon. The system employs a device for sensing the presence of a glass sheet and activating an ultraviolet light, which is modulated and illuminates the surface of the glass sheet. A visible light detector intercepts light fluorescing from the illuminated sheet surface, producing a signal which is processed by an electronic network for indicating the presence of metallic oxides on the sheet surface. When fluorescence is detected the ultraviolet light is extinguished and when fluorescence is not detected an alarm is activated.
