This article highlights the importance of flatness in precision optics, beyond just surface quality. Learn how aspect ratio—the relationship between an optic’s size and thickness—directly impacts stability, with high ratios making flatness harder to maintain. It also describes the “potato chip effect,” a common warping deformation in thin optics that can degrade system performance at even nanometer scales.
