The invention relates to a device for measuring panes. The device comprises a light source and a light sensor which are arranged in such a way that a light beam emitted from the light source passes through the pane and impinges on the light sensor. According to the invention, the light beam has a linear polarization, wherein the polarization direction forms an angle of between 50° and 130° with an incidence plane stretching between the axis of the light beam and the pane normal at the point at which the light beam impinges on the pane. The light sensor is dimensioned such that both a primary beam and a secondary beam of the light beam impinge on the light sensor. The invention also relates to a corresponding method. According to the invention, the second beam has an increased brightness, so that it is easier to measure both beams.
A device for measuring panes, comprising a light source and a light sensor, which are arranged in such a way that a light beam emanating from the light source passes through a pane and is incident on the light sensor, wherein the light beam has a linear polarization and in that a polarization direction of the light beam includes an angle of between 50° and 130° with a plane of incidence, which is defined by an axis of the light beam and a normal of the pane at a location at which the light beam impinges on the pane, and in that the light sensor is dimensioned in such a way that both a primary beam and a secondary beam of the light beam are incident on the light sensor.
