Claim One:
1. A hand-held inspection tool, the tool comprising: a tool body, a sensing head connected to the tool body, the sensing head comprising: (a) a video camera; (b) a video camera lens fitted on the video camera and exposed on a face of the sensing head; (c) at least one spectral band-pass video camera filter covering the video camera lens, the video camera filter being structured so that only a selected wave band of light passes through the at least one video camera filter to the video camera lens; and, (d) at least one excitation light disposed on the face of the sensing head, the at least one light being structured to induce target contamination to emit fluorescence corresponding with the selected wave band of light that passes through the at least one video camera filter to the video camera lens; a video processor receiving and transmitting the video images from the video camera; a visual display receiving and displaying the images from the video processor; and, a hand grip for supporting the tool body and the sensing head; wherein an operator moves the inspection tool via the hand grip to the target contamination and directs the at least one light so that the fluorescence emitted by the target contamination is detected and transmitted by the video camera and shown on the visual display.
