The equipment and methods used to produce wide-angle antireflection coatings based on Reststrahlen materials are described. The optical constants of the coating materials used in the construction of the multilayers were determined by spectrophotometric ellipsometry and are compared with the literature values. The measured performance of an experimentally produced antireflection coating is compared with the expected calculated performance. The reflectance is low over a wide range of angles, but only in the narrow-wavelength region at which the refractive index of the Reststrahlen material is close to unity.
描述了用于制备基于Reststrahlen材料的广角减反射涂层的设备和方法。通过分光光度椭圆偏振法测定了用于构建多层膜的涂层材料的光学常数,并与文献值进行了比较。将实验制备的减反射涂层的测量性能与预期的计算性能进行了比较。在很宽的角度范围内反射率都很低,但仅在Reststrahlen材料的折射率接近1的窄波长区域内如此。
