MarForm MFU 200 Aspheric 3D Precision 3D Measuring Station DESCRIPTION Mahr developed the MarForm MFU 200 Aspheric 3D to enable optical components to be tested in 2D / 3D quickly and close to the production area. MarForm measuring machines have been recognized for decades for their accuracy and stability. With the MarForm MFU 200 Aspheric 3D, this experience has now become available to the optical industry. Accuracy • The MarForm MFU 200 Aspheric 3D is a precision measuring instrument. Its very low measurement uncertainty is ideally suited to your process optimization requirements. Measuring principle • The MarForm MFU 200 Aspheric 3D measures the topography of optical components. Of course, a quick 2D measurement can also be recorded with a profile across the zenith of the lens. For 3D measurements, two linear profiles offset by 90° are first measured across the zenith of the lens in a single sequence. Then, multiple concentric polar profiles are recorded by rotating the C axis. These measuring points are used to generate a topography. Interrupted surfaces can be measured with the fully positionable probe arm. • Using the measuring station in a vibration-cushioned cabinet keeps external interference, such as vibration and dirt, away from the measuring objects. MarWin is the software used for operation and analysis. Measuring procedure • Before starting the measurement, choose the nominal form type and set the parameters for the expected reference lens. In the next step, the measuring data is recorded and compared with the nominal data for the lens. • The RMS value, PV value and slope error are shown as parameters. • In the software, the individual parameters for the aspheres, such as the radius of curvature R0, conical constant k and the aspheric coefficients Ai, can be adjusted to the measuring results when adjusting the nominal asphere to the fit asphere. • The differential topography between the measured values and the nominal lens is displayed as a color coded line chart. The 2D profiles and the differential topography can then be exported in known formats for correction for the machine tool. • In addition to measuring spheres and aspheres as described above, other rotationally symmetrical objects can also be measured and evaluated using the nominal form as a conical profile or Sagitta description of a 3D scatter plot. 3D visualization of target/actual comparison For more information, please visit our website: www.mahr.com MarOpto | Measuring Instruments for the Optical Industry 585
