Abstract
The invention concerns a laminated glazing with an optically transparent area () comprising (i) at least one inner () and one outer () glass sheets, each having an internal and an external faces, and being high level of near infrared radiation transmission glass sheets, (ii) at least one thermoplastic interlayer () to laminate the at least the inner and the outer glass sheets, comprising at least a first zone () and a second zone (), the second zone () being delimited by the optically transparent area (), and (iii) at least ne optical sensor device () provided on the inner face of the inner pane integrated in the optically transparent area (). According to the present invention, the thermoplastic interlayer comprises a second zone () delimited by the optically transparent area where the laminated glazing has a value of infrared transmission TIR1 higher than the value of infrared transmission TIR2 of the first zone () for the working wavelengths of the optical device.
