Abstract
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.
