LUPHOScan SD

Non-contact 3D Surface Profilers for Form Measurement of aspheres, spheres, flats and slight freeforms Optical Surfaces

The LUPHOScan is designed to perform ultra-precision non-contact 3d surface form measurement of rotationally symmetric surfaces (optics) such as aspheric lenses, spheres, flats and slight freeform. Key benefits of the profiler/equipment include fast measurement speeds, high flexibility with regard to uncommon surface shapes (e.g. flat apexes or profiles with points of inflection).

The LUPHOScan is available in various sizes and in measuring configurations. The platform size determines the maximal object diameter that can be measured. Maximal measurable diameters are 120, 260, 420 and 600 mm.

  • Overview +


    LUPHOScan SD platforms are interferometric, scanning metrology systems based on MWLI® technology (multi-wavelength interferometry). They are designed to perform ultra precision non-contact 3D form measurements mainly of rotationally symmetric surfaces such as aspheric lenses. 

    LUPHOScan SD platforms enable straightforward form measurements of aspheres, spheres, flats and slight freeforms. Key benefits of the systems include fast measurement speeds, high flexibility with regard to uncommon surface shapes (e.g. flat apexes or profiles with points of inflection), and maximum object diameters up to 420 mm. 

    LUPHOScan SD systems offer crucial benefits with regard to 3D form measurements of high quality optical surfaces.
    • Investigation of any rotationally symmetric surface
    • Ultra high, reproducible accuracy
    • Almost every material  - Transparent, specular, opaque, polished, ground
    • Large spherical departures
    • Fast measurement speeds
    • Diameters - Up to 120mm, 260mm, or 420mm

    LuphoSwap extension - Complete form error characterisation of optical parts 

    LuphoSwap is an extension available for LUPHOScan SD and LUPHOScan HD platforms that enables complete characterisation of both surfaces of a lens. The two surfaces are measured successively. A unique measurement concept enables absolute correlation of the results measured on both sides. That is, at the same time as the form errors are measured this tool determines the exact lens thickness, the wedge and decentre errors of the two surfaces and their rotational orientation. In addition, the lens–mount positioning can be assessed. This powerful tool is based on the absolute measurement capability of the LuphoSmart sensor technology, a unique holder concept, and on an additional (runout) reference sensor.
