Abstract
An inspection lamp for detection of a fluorescent material which absorbs electromagnetic energy in a specific excitation frequency band and which emits electromagnetic energy in a specific fluorescent emission frequency band within the visible light spectrum. The lamp includes a bulb housing, a light source within the bulb housing, and a dichroic filter. The dichroic filter is adapted to transmit electromagnetic radiation in the excitation frequency band of the fluorescent material and reflect electromagnetic radiation in the fluorescent emission frequency band of the material.
