LUPHOScan 850 HD

The world’s most versatile, non-contact 3D form measurement platform for advanced large diameter optical surfaces



The LUPHOScan 850 HD 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 and high flexibility with regard to uncommon surface shapes (e.g. flat apexes or profiles with points of inflection).

  • Overview +


    Taylor Hobson are pushing the boundaries of large optics metrology. Our expert metrologists are delighted to announce the launch of the LUPHOScan 850 HD

    Built on the foundations of the world renowned LUPHOScan HD platform, the LUPHOScan 850 HD delivers stable non-contact metrology for large complex optics applications.

    The instrument has been developed working and listening closely to our many partners in optics manufacturing. Our metrologists understand the importance designing a system that delivers highly accurate, repeatable and reliable measurement data.
