摘要

A simple and practical model is used to analyse the influence of substrate surface defect on the optical charac teristics of a single-layer coating. A single-layer coating is prepped and its optical properties are fitted. Some explanations for the origin of the transition layer are presented. It is concluded that there is a transition layer forming between the substrate and coating, which is attributed to substrate surface defects, and its refractive index change is nearly of linearity.
