Aspects of Radiometry and Process Verification for 3-D UV Processing

As larger and more complex objects are candidates for UV-curable coatings, the challenges of exposing curable surfaces to adequate UV energy become greater. It is desirable to position UV lamps for the most effective exposure, and the least wasted energy. Because complex parts differ from one another, and paint line organization varies, lamp configurations unique to each line or part type may be necessary. Techniques of radiometric verification of UV exposure to all complex curable surface areas are explored, including radiachromic films.
