Abstract
A compact hand-held high intensity ultraviolet inspection lamp having a straight handle aligned with beam direction includes a high-intensity light bulb enclosed within a bulb housing, a light-emitting aperture at the end of the bulb housing away from the handle, and an ultraviolet light filter in alignment with the aperture to absorb substantially all light emitted from the bulb at frequencies outside of the ultraviolet spectrum and to transmit the unabsorbed ultraviolet light. Three embodiments of such lamp are disclosed herein.
