  • How to Analyze Prepared and Unprepared Geological Samples with One Digital Microscope

    Polarized light microscopes have been used in classical earth science studies for the last 100 years. Since then a lot of progress has been made to increase the user friendliness, ergonomy, and optical performance of such microscopes. Still, one thing has not changed: Classical polarized light (compound) microscopes can only be used for prepared samples, because the working distance they offer is insufficient for whole samples. This article explains how earth scientists can analyze prepared and unprepared samples for polarized light applications with one single instrument, namely the Leica DVM6 M digital microscope. With the right choice of accessories it serves as a semi-quantitative polarization microscope.

  • Webinar: Innovative Sample Preparation Method of Heterogeneous Materials for EM Observation

    Sample Preparation is a prerequisite for microscopy. It’s essential for achieving accurate and reproducible results. To get the best results in interfacial characterization, Leica Microsystems developed a triple ion beam cutting technique for electron microscopy observation. This technique is integrated into the ion beam slope cutter Leica EM TIC 3X and optimizes the processing conditions of sample preparation to reveal the nano-sized interfacial features of the specimen.

  • 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.

  • 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?
