As optical components increase in size, so do the challenges involved in producing them. For example, maintaining coating uniformity across large apertures becomes significantly more difficult, and even slight deviations can degrade system performance, distort beam profiles, or introduce phase shifts. Optical surfaces must meet extremely high-quality standards at the microscopic scale, as even tiny defects can trigger laser-induced damage at much lower fluence levels. To address these challenges, optical performance at this scale requires advanced substrate polishing techniques and sophisticated coating processes, such as magnetron or ion beam sputtering.
