Abstract: A laminate includes at least two sheets, one of the at least two sheets including a colored glass and another of the at least two sheets being a further sheet. The sheet including the colored glass in a wavelength range from 875 nm to 1600 nm has an internal transmittance at at least one wavelength of at least 75%. A connecting layer is disposed between the at least two sheets. The laminate has a thickness of at most 6 mm. The laminate in a wavelength range from 400 to 700 nm has an average transmittance τavg,400 nm to 700 nm of less than 15% where τavg,400 nm to 700 nm is defined as

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.
