Kati Stranius, PhD, has started research at Oplatek. The objective of her study is to optimize the process of thin film coating at Oplatek. By studying the process and identifying the origin and sort of occurring surface defects it is possible to further enhance the optical quality of thin film coating. This will enable the manufacturing of thin film coating that meet the highest quality standards needed in demanding applications, such as high-power lasers. Stranius will also examine new materials and alternative processes to manufacture thin film coating to produce optimal and more stable coatings.
