高反射涂层在许多物理实验中都有应用。尽管光学镀膜的质量很高，但由于镀膜层中的微米级缺陷引起的散射光改变了反射镜的性能。这篇论文的主题是研究在最先进的高灵敏度光学实验中使用的镜面的特定涂层中存在的点状散射体。我们研究了材料在不同厚度下的行为以及退火后产生的缺陷。据我们所知，这是第一次洞察到不同材料和厚度的这种缺陷的形成，以及当样品退火时如何减少这种缺陷。
High-reflective coatings are used in many physics experiments. Despite the high quality of the optical coating, the performances of the mirrors are altered by the scattered light induced by micrometer size defects in the coating layers. The topic of this paper is the study of the point-like scatterers present in the specific coating of the mirrors used in state-of-the-art, high-sensitivity optical experiments. We studied the behavior of the materials according to different thicknesses and the resulting defects after annealing. To the best of our knowledge, this is the first insight into the formation of such defects for different materials and thickness and how this is reduced when samples are annealed.
