Device for reference related measurement of form and structure of aspherical lens, has length measuring sensor comprising sensor bodies connected with each other using rigid bond bridge and connected to sensor holder

摘要

The device has a table surface for receiving a test specimen object and a reference object. A sensor holder is movable in a spatial axis. A length measuring sensor has a sensor bodies connected with each other using a rigid bond bridge. The measuring sensor is connected to the sensor holder. The rigid bond bridge is arranged parallel to the table surface. The sensor holder is rotatably supported around an axis standing perpendicular to the table surface. The table surface and/or the distance sensor are movably supported parallel to each other.
