Abstract

Abstract The presence of native oxide layers on aluminum mirrors can be a nuisance for precision optical design. As the native oxide thickness varies from mirror to mirror, its effect cannot be completely canceled even in the conventional crossed fold mirror geometry. We show how this effect arises and how it can be mitigated, and provide an experimental demonstration in which the residual linear retardance and linear diattenuation are reduced to <0.14° and <0.001, respectively, over the visible and near-infra-red spectral range.

天然氧化层对可见光至近红外区域反射镜偏振抵消的影响

摘要铝反射镜上天然氧化层的存在会给精密光学设计带来麻烦。由于天然氧化物的厚度随镜面的不同而不同，即使在传统的交叉折叠镜面结构中，其影响也不能完全消除。我们展示了这种效应是如何产生的以及如何减轻它，并提供了一个实验演示，其中在可见光和近红外光谱范围内，残余线性延迟和线性双衰减分别减少到<0.14°和<0.001。
