Software solutions for asphere measurements

Mahr bietet Softwarelösungen für die Messungen von Optiken.

Mahr offers software solutions for the measurement of optics.


Software for analysis of measurements on aspheres and other optical components is an important part of the industry solution from Mahr for the optics industry. The particular requirements of measuring tasks on optics are already stored in these software solutions. The software ensures that the measurement results are shown meaningfully and documented. For each individual measuring system, Mahr provides a precisely matching software.

As an industry solution for the optics industry, the application specialist provides alongside specific measuring systems also the appropriate software. It processes the measurement results of the specific measurement tasks, clearly depicts them and is the basis for the documentation of the measurements. Mahr has developed its own software solutions for the different measurement systems:

IntelliWave – for MarOpto Fizeau interferometer
The software IntelliWave allows the measurement and analysis of spherical and aspherical lenses, machined ceramic surfaces and semiconductors. Wavefronts, flatness, irregularities and radii of curvature can also be measured. The software enables, for example, "Peak-to-Valley" - and RMS measurements, Zernike, Seidel and diffraction analyses. The measurements of curvature radii and aspheres are simplified by Wizards. The software supports and also enables automated measurements directly in the production. It provides interfaces for IDL ™, MS Excel ™ and LabVIEW ™.

Aspheric.lib – the evaluation software for MarSurf LD 130 / LD 260 Aspheric 2D / 3D and MarForm MFU 200 Aspheric 3D.
The measurement and evaluation software Aspheric.lib is used to analyze and graph form or or pitch errors of aspherical lenses. They calculated parameters such as radius of curvature, conic constant and aspherical coefficients. The nominal form type and the parameters of the of the expected nominal lens are entered into the software before a lens is measured. In the next step, the measurement data are recorded and compared with the nominal data of the lens. The parameters displayed are radius, RMS value, PV value and pitch errors. The differential topography between the measuring values ​​and the nominal asphere is output as a color-coded height image. The 2D sections and the difference topography can be exported into popular formats to correct the processing machine (2D / 3D).
In addition, the stitching option is offered. The detected linear profiles of the asphere are automatically combined with an exact alignment of the angular positions and also the offset in the measuring direction. This is possible for convex as well as concave surfaces with an aspherical shape, such as gullwings.
