Abstract
The monitoring of energy radiating from a heated material, such as a hot melt adhesive, dispensed onto a substrate may be accomplished by an infrared sensor. The wand of the infrared sensor is located downstream of the dispensed material for receiving the radiant energy. The wand is provided with internal air for cooling and for providing laminar air flow in the vicinity of the lens to prevent the accumulation of airborne contaminants on the lens. The wand is also provided with a light aiming device.
