Abstract

A laminated motor-vehicle windshield includes exterior glass sheet and an interior glass sheet, which sheets are joined together by an interlayer made of a thermoplastic of refractive index n1. The windshield is equipped with a through-hole that passes through at least one of the glass sheets and may pass through the interlayer and wherein the hole is filled with an optical device that is suitable for deviating a light beam incident substantially horizontally on that face of the windshield which is exposed to the exterior of the vehicle and for making it converge, substantially without deformation, on an image-capturing device of a camera, such as a CCD or CMOS detector, placed facing that face of the windshield which is turned toward the passenger compartment of the vehicle. The detector is arranged substantially parallelly to the surface of the windshield.
