The mobile wedge angle sensor WAS-P is used to determine the wedge angle and the radius of curvature of glass panes, e.g. of windscreens of automobiles, helicopters, airplanes or rail vehicles.

In automotive engineering, the parameters wedge angle and radius of curvature are important when important information is reflected in the driver’s field of vision using special projectors. If the parameters differ noticeably from the required values, double images or blurred images can result, which make the projection system unusable. The WAS-P enables simultaneous measurement of the wedge angle and radius of curvature parameters with just a single sensor. An optionally available manual positioning system enables the exact, repeatable positioning of the sensor on built-in windscreens.
