WebRoughness describes high spatial frequency errors, meaning very small deviations on the order of Angstroms (10 -10 m). Understanding the surface roughness of optical surfaces is critical to control light scatter, as scatter can be proportional to the surface roughness of the optics. Light scattering and absorption from surface roughness have a ... WebHow are roughness and wettability related?. Roughness affects the wettability of a solid and thus the contact angle of a liquid as well as adhesion. A rule of thumb states that roughness improves wettability at small contact angles (angle becomes smaller), and reduces it at large contact angles (angle becomes larger). The limiting contact angle of wettability, …
