Abstract

The use of camera-based security systems is growing at an accelerated rate in modern cars. As the industry moves towards the development of vehicles with full autonomous capacity, the number of cameras required and their resolution increase. In the same way, the windshields where said cameras are mounted are getting bigger and more complex shapes. However, this can cause problems in the camera's field of vision. Variations in the thickness of the glass and the plastic adhesive layer, the surface mismatch, the texture, the design curvature along with the installation angle that is usually minimal, can reduce visual clarity. These optical aberrations are further exacerbated during the lamination process when all three layers are forced to join under pressure. The laminate of the invention has a cut-out 8 in the plastic adhesive layer 4, according to the field of vision of the chamber. A removable insert 14 is placed in this portion of the laminate to prevent breakage during the rolling process. Then, the insert 14 is removed and the vacuum left is filled with lamination resin 16 and the resin 16 is cured. The result is a laminate with superior optical quality.
