Abstract

Holographic mirrors within laminated windshields are used to increase the reflectivity of a windshield or parts of it for a defined spectral wavelength band and for specific angular directions, while its transmissivity in the remaining spectral region is nearly unchanged. A narrow-band, highly reflective holographic mirror serves as a combiner for a car head-up display. Large-sized, broadband holographic mirrors are used to realize a solar protective glazing with direction-dependent transmissivity in the visible spectral range. The holograms are mass-producible and withstand the lamination process for safety glass windshields.
