Delivering ultraviolet light from the lamp to the actual target area is just as important as generating light in the first place. With spot curing systems, a number of optical and engineering issues require appropriate consideration to maximize collection and delivery of output from the lamp. In particular, poor coupling of the lamp output into the optical delivery system is a very important barrier to high system efficiency. Optical energy that cannot be delivered to the target will be converted into heat. Systems that do not exhibit high optical efficiency will run hotter, which can have a direct impact on the service life of the arc lamp and can cause premature degradation of liquid filled light guides. Both of these consequences contribute to increased operating and maintenance costs for the system, resulting in a higher cost per finished assembly.
