The MicroGlider® Asphere employs a unique method to perform highly precise profile measurements on spherical and aspherical lenses. The lens is fixed by a holder, which is mounted on an air bearing rotary table. The system configuration is such that the sensor is always perpendicular to the lens surface, which is rotated during measurement. The measured data are recorded as polar coordinates (r,φ) and are then visualized with the help of the analysis software. This system is also available as a 3D version.
