A privacy glazing structure may be fabricated from multiple panes of transparent material that hold an optically active material and also define a between-pane space that is separated from a surrounding environment for thermal insulating properties. The privacy glazing structure may include various functional coatings and intermediate films to enhance the performance and/or life span of the structure. For example, the privacy glazing structure may include a low emissivity coating and a laminate layer positioned between an optically active layer and an exterior environment exposed to sunlight. The low emissivity coating and laminate layer may work in combination to effectively protect the optically active layer from sunlight degradation. Additionally or alternatively, the laminate layer may impart safety and impact resistance properties to the structure.

The use of camera based automotive safety systems is growing at a rapid rate. As the industry moves towards full autonomous capability, the resolution and number of cameras required is increasing. At the same time windshields, behind which many of the cameras are mounted, are becoming larger and more complex. Achieving acceptable optical quality can be challenging due to continually evolving optical requirements generated by the rapid development of camera systems and processing algorithms as well as variations in the index of refraction, curvature, bend, thickness, and other variables. The laminate of the disclosure has a portion of the inner glass layer removed in the camera field of view and replaced with a high optical quality insert bonded to the glass. This allows for much greater optical quality, while retaining durability and functionality of a standard laminate.
