Intertronics’ (Kidlington, U.K.) BlueWave 200, a high-intensity UV spot-curing lamp, features a new (pat. pend.) Intensity Adjustment that enables simple, manual modifications to UV intensity during initial UV process validation and production. This permits engineers to evaluate the full range of intensity produced by the lamp, from 0 percent to 100 percent. Thus, the upper and lower intensity limits of a UV curing process can be identified in an actual production setting. In production, routine radiometer measurements determine if any further intensity adjustments are required. Reportedly, the average bulb varies less than 1 percent over eight hours of normal use. The useful bulb life ranges up to 2,000 hours with 20W of UV/visible light curing power, coupled with a choice of two, three or four split wand light guides. The lamp primarily emits UVA and blue visible light (300 to 450 nm) and is designed for UV curing of adhesives, coatings and encapsulants. It contains an integrated shutter that can be actuated by a foot pedal or PLC, making it suitable for manual and automated processes.
