  • Assessing the Surface Metrology of Orthopaedic Implants

    Monday, October 22, 2018 |

    Surgical implants represent some of the greatest steps forward in medical innovation of the last century. Orthopaedic surgeons routinely custom-build medical implants to replace missing joints or bones in the skeletal structures of patients. Dental implants comprised of artificial veneer material and a false, titanium root are increasingly commonplace. Cardiothoracic surgeons can replace damaged or diseased tissue in the human heart and implant false heart valves with life-saving ramifications.

  • What are Form Measurements?

    Monday, October 8, 2018 |

    A form measurement is conducted to determine the overall shape of an object under test, which may refer to its flatness, straightness, parallelism, roundness, or cylindricity. This is critical for ensuring that the component will fit in the end-product application, which is in turn key for ensuring product performance and maintaining customer satisfaction.

  • Metrology Instruments: Outlining the New Form Talysurf® PGI NOVUS

    Wednesday, September 26, 2018 |

    Form, roughness, and topography are most commonly measured using contact metrology instruments, which acquire surface profiles by moving a sensitive stylus across the measured component in a pre-defined direction. A diamond tip with micrometre (μm) dimensions acquires variations in resistance to applied pressure, but this is typically limited to variations across a single plane.

    Tuesday, September 18, 2018 |

    Surface profilers are used to measure and characterize the surface features of a material on the micro- and nanoscale. These minute topographical features are typically categorized as roughness, waviness, or directional lay, representing potentially microscopic structure superimposed on the true form of a material’s substrate.

  • What are Microptic Clinometers?

    Wednesday, August 8, 2018 |

    A clinometer is an optical device designed to measure the angular profiles of a surface against a vertical or horizontal reference. This enables precision measurement of surface elevation, depression, and tilt which are fundamental properties for successful leveling and alignment of components.

  • What is a Surface Profiler

    Wednesday, July 18, 2018 |

    A surface profiler is a metrology instrument for topographical characterization of a product’s uppermost layers. It is a multipoint form of measurement that considers a material’s primary form and the sub-micron (μm) textural variations of its surface, which are typically characterized as dimensional fractality and surface roughness. These features may contribute to a directional lay, or a pattern, which can have a distinct impact on the physical properties of the material under observation.
