Mahr Tilted Wave Interferometer - MarOpto TWI 60

The Mahr Tilted Wave Interferometer (MarOpto TWI 60) is a highly flexible interferometer for the quick and high precision measurement of aspheres. The novel non-contact metrology system uses 'Tilted Wave Front Interferometry (TWI)' which makes use of the multi-axis flexibility and accuracy of hexapod parallel kinematics 6-axis motion systems to position a calibration sphere. The new measurement method, implemented by Mahr combines speed and flexibility into one process. The MarOpto TWI 60 machine can measure surface shapes with high lateral resolution directly on the production line with a measuring uncertainty of less than 50 nanometers. The metrology system acquires several subapertures that are active at different times and combines the individual interference patterns to form a single pattern.
