  • The Effects of Peri-implantitis Decontamination Treatments on the Surface Roughness and Chemistry of a Titanium Alloy Used for Dental Implants: Implications for Bone Reintegration

    Titanium (Ti) alloys are biocompatible materials which are often used for human implants, especially in dentistry. For this study, different types of odontological (dental) treatments for peri-implantitis, an infection of the gum and dental tissue around the implant, were performed on a Ti-6Al-4V (TAV) alloy, typically used for implants, to study the effect on its surface roughness and chemistry.

  • Brief Introduction to Surface Metrology

    Surface metrology is the science that deals with measuring topography. Characterization of a surface with its amplitude, spacing and shape of its features, is called "topography". The term "topography" is derived from Greek roots; "topo-" meaning place and "graph-" describes a type of symbolic diagram.

  • Automated Digital 3D Topography Measurement with the Leica DCM 3D Dual Core Measuring Microscope

    The precise measurement of surface structures and topography is the key thing during the production, control and development in many sectors of industry or research. Because very often there is not possible to use some contact methods for performing this task new optical methods based on interferometry and confocal technology started to be available for non-contact surface metrology in the recent years.

  • 3D Visualization of Surface Structures

    One of the main features of a digital microscope is the speed and ease with which it enables surface models to be created of macroscopic and microscopic structures. In a qualitative evaluation, these provide a better understanding and a more detailed documentation of the specimen. In addition, quantification of the surface provides valuable information about the composition of the surface and its wear. Which specimens are suitable for use with a Leica digital microscope, and what are the limitations of the method used?

  • 3D Surface Measurement: Characterization of Solar Cells

    Solar energy is becoming more and more important all around the globe. Not only is it available in unlimited supply, it also offers key advantages for protecting the climate and the environment. Every year, many thousands of solar cells are produced worldwide for new photovoltaic plants. An important criterion for quality control is 3D characterization of the light-absorbing surface. In the past, this required time-consuming SEM analysis. A Dual-Core 3D Measuring Microscope that combines confocal and interferometry technology offers non-contact, high-precision analysis of the surface texture of solar cells in a matter of seconds.

  • No Defect Goes Undetected - Inspection of Micro-optic Components

    Micro-optic components are used in a host of products concerned with illumination or imaging. Quality control of these components is challenging, as inspection has to be highly accurate yet non-invasive. Combining confocal and interferometric technology, the Leica DCM 3D Measuring Microscope is equipped to characterize these components with nanometer precision and ultra fast speed, despite the fact that they often have polished and curved surfaces that are difficult to examine.
