Mahr Federal has introduced a new high-precision 2-D/3-D measuring station for checking contour and surface topography of aspheric optical lenses and other components during multi-stage grinding and polishing operations. The MarSurf LD 130 and 260 Aspheric units feature high measuring speed, measuring range of up to 260 mm, vertical resolution of 0.8 nm, and form deviations of less than 100 nm. As with all Mahr metrology systems, the MarSurf LD 130 and 260 Aspheric are backed by Mahr’s extensive worldwide service and application support network.MeasurementSystem_IN

The MarSurf LD 130 and 260 Aspheric facilitate the multi-set grinding and polishing manufacturing process for high precision optics by providing fast accurate 2-D and 3-D measurements for the evaluation of contour and surface topography. The system can be used for spherical and aspherical lenses, as well as many types of cylinder lenses, lens mounts, housings, and other mechanical components. Measuring speed is up to 10 mm/s for large lenses, and down to 0.02 mm/s for micro lenses.

The MarSurf LD 130/260 Aspheric includes a new probe system with a biomimetic probe arm design that provides increased stiffness, damping, and lower moment of inertia. A chip integrated in the probe arm provides probe identification and parameters, and verification of correct mounting position, allowing probe arms to be changed without recalibration. Automatic probe positioning allows even discontinuous surfaces to be measured.
