Project description
In advanced manufacturing (e.g., semiconductors, OLEDs), production is shifting to shorter wavelengths. Under UV irradiation, optics suffer fatigue that shortens lifetime, yet the effect is poorly understood. This project will model the mechanism and develop in-situ measurement systems to monitor individual optics, enabling studies of commercial components and optimisation of functional coatings. By quantifying fatigue and correlating it with accessible metrics (e.g., laser-induced damage threshold), we aim to derive design rules that extend component lifetime and make deep-UV processes economically viable.
