Claim 16:
17. A laminated glazing with an optically transparent area comprising:
at least one inner glass sheet and one outer glass sheet, each glass sheet having an internal and an external face;
at least one thermoplastic interlayer to laminate the at least one inner and outer glass sheets, comprising at least a first zone and a second zone, the second zone being delimited by the optically transparent area; and
at least one optical sensor device provided on the inner face of the inner glass sheet integrated in the optically transparent area,
wherein in the second zone of the theimoplastic interlayer delimited by the optically transparent area the laminated glazing has a value of infrared transmission TIR1 higher than a value of infrared transmission TIR2 of the first zone for working wavelengths of the optical sensor device, and
wherein the thermoplastic interlayer comprises the first zone made of polyvinyl butyral covering a main surface of the glazing and provided with a frame wherein a piece of thermoplastic interlayer of the second zone is selected from the group consisting of ethylene vinyl acetate, Cyclic olefin polymer (COP), and polyurethane and is placed inside the frame.
