Laminated glazing and process

A process for producing a shaped laminated glazing, the process comprising,

• providing a first glass substrate having a first surface and second surface and a second glass substrate having a third surface and a fourth surface,
• applying a first obscuration layer to at least a first portion of the first or second surface of the first glass substrate, the first obscuration layer comprising at least one first sensor window portion having a controlled first sensor window portion optical distortion,
• applying a second obscuration layer to at least a first portion of the third or fourth surface of the second glass substrate, the second obscuration layer comprising at least one second sensor window portion having a controlled second sensor window portion optical distortion,
• optionally, shaping the first glass substrate and the second glass substrate by heating the first glass substrate and the second glass substrate to a temperature above 570° C.,
• placing at least one polymer ply between the first and second glass substrates, and
• laminating the first glass substrate, the polymer ply and the second glass substrate,
• wherein the first sensor window portion has an x axis dimension and/or a y axis dimension, and the second sensor window portion has an x axis dimension and/or a y axis dimension, wherein the x axis dimension and/or the y axis dimension of the first sensor window portion is different to the x axis dimension and/or the y axis dimension respectively of the second sensor window portion,
• wherein the x axis dimension of the first window portion is greater than the x axis dimension of the second window portion, and/or the y axis dimension of the first sensor window portion is greater than the y axis dimension of the second sensor window portion,
• wherein the smaller window portion is located so that there is an offset at each end of the x and/or y axis dimension relative to the larger window portion,
• wherein the offset at one end of the x or y axis dimension is different from the offset at the respective other end of the x or y axis dimension,
• thereby allowing control of the first sensor window portion optical distortion and the second sensor window portion optical distortion such that the absolute magnitude of the optical distortion of the sensor window is lower than the absolute magnitude of the first sensor window optical distortion and the second sensor window optical distortion.
