摘要:
A partial beam splitter includes a substrate including a substrate material; and a coating arranged on at least one main surface of the substrate. Along a first direction which is parallel to a normal vector of the main surface, the substrate and all coatings having a total thickness. For a specific light beam having a specific wavelength within a range of 450 nm and 650 nm which is incident on the partial beam splitter along a second direction with an angle of 32° enclosed between a vector pointing in the first direction and a vector pointing in the second direction, the specific light beam after transmitting through the partial beam splitter has a phase having a phase difference of an absolute value of smaller than or equal to 30° compared to the case in which, under otherwise identical conditions, the partial beam splitter is replaced by a similar reference substrate.

摘要:
A coated substrate is provided with a scratch-resistant anti-reflective coating. The anti-reflective coating is designed as an optical interference coating that has at least two low refractive index layers and at least one high refractive index layer. The high refractive index layer is a transparent hard material layer and includes crystalline aluminum nitride with a hexagonal crystal structure with a (001) preferred orientation. The low refractive index layers include SiO2. The low refractive index layers and high refractive index layers are arranged alternately.
