The use of camera based safety systems is growing at a rapid rate in modern automobiles. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. This presents problems in the area of camera optics. Variations in the thickness of the glass and the plastic layer, surface mismatch, surface texture and the design curvature of the glass in conjunction with the often low installation angle, can reduce the optical clarity of the camera optics. These optical aberrations are further exacerbated during the lamination process when the layers are bonded together under pressure. The laminate of the invention utilizes a cutout in the plastic bonding layer in side of the laminate, preferable in the camera field of view. A laminating resin is used to fill the gap left by the cutout between the two glass layers.

A laminated window assembly has a first glass pane with a coating formed thereon, a second glass pane, and a polymeric interlayer provided between the first glass pane and the second glass pane.
