For certain applications, such as the production and maintenance of automobiles, aircraft, or power plants, quality control and reliability assurance, as well as safety and health inspection, accurate and reliable image data with precise calibration are very important. Digital microscopes are appealing for a wide range of technical applications in various industries, such as automotive, aerospace, precision engineering, microelectronics, and medical devices. https://www.leica-microsystems.com//science-lab/are-your-digital-microscope-measurements-accurate-and-reliable/ Mon, 08 Sep 2014 11:01:00 +0000 PhD James DeRose, Georg Schlaffer https://www.leica-microsystems.com/13490 Surface Metrology Characterization of Thin Films Using High Definition Confocal Microscopy Thin film characterization technologies are in high demand, given the wide-spread use of coatings in all engineering and science fields. The properties of thin films can vary dramatically, i.e. thickness, optical and electrical properties, hardness, etc., that is difficult to find a general purpose characterization technique. https://www.leica-microsystems.com//science-lab/characterization-of-thin-films-using-high-definition-confocal-microscopy/ Thu, 05 Jun 2014 10:52:00 +0000 MSc Marco Renzelli, PhD Edoardo Bemporad https://www.leica-microsystems.com/12648 Surface Metrology Quality Assurance Digital Microscopy 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. https://www.leica-microsystems.com//science-lab/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/ Wed, 19 Feb 2014 11:22:00 +0000 PhD Jordi Diaz-Marcos, MSc Joan Vilana Balastegui, DDS, MS, PhD Angel F.

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. https://www.leica-microsystems.com//science-lab/automated-digital-3d-topography-measurement-with-the-leica-dcm-3d-dual-core-measuring-microscope/ Fri, 17 May 2013 09:39:00 +0000 https://www.leica-microsystems.com/6596 Digital Microscopy Quality Assurance 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? https://www.leica-microsystems.com//science-lab/3d-visualization-of-surface-structures/ Wed, 19 Sep 2012 22:00:00 +0000 Daniel Goeggel, Georg Schlaffer https://www.leica-microsystems.com/5141 Digital Microscopy Quality Assurance Trends in Microscopy There are digital cameras, digital TV sets, digital picture frames, digital schools on the internet. Cryptologists design digital signatures, communication researchers speak of digital identity. Digital may be an overused buzzword, but digital technology has undeniably revolutionized our world ever since the invention of the computer and will continue to do so in future. https://www.leica-microsystems.com//science-lab/trends-in-microscopy/ Wed, 19 Sep 2012 22:00:00 +0000 Daniel Goeggel, Dipl. oec.-troph. Anja Schué https://www.leica-microsystems.com/8076 Surface Metrology Digital Microscopy Quality Assurance 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. https://www.leica-microsystems.com//science-lab/3d-surface-measurement-characterization-of-solar-cells/ Mon, 27 Apr 2009 22:00:00 +0000 Roger Artigas https://www.leica-microsystems.com/8078 Surface Metrology Quality Assurance Digital Microscopy 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. https://www.leica-microsystems.com//science-lab/no-defect-goes-undetected-inspection-of-micro-optic-components/ Tue, 14 Apr 2009 22:00:00 +0000 Roger Artigas https://www.leica-microsystems.com/8080 Surface Metrology Quality Assurance 3D Measuring Microscope Combines Confocal and Interferometry Techniques In recent years, interferometers and optical imaging profilers based on confocal technology have been competing fiercely to conquer the non-contact surface metrology market. They are both capable of accurately and reliably measuring surface topographies on a millimeter to nanometer scale. Leica Microsystems presents a complete solution which combines both confocal and interferometry techniques: the Leica DCM 3D Dual-Core 3D Measuring Microscope. https://www.leica-microsystems.com//science-lab/3d-measuring-microscope-combines-confocal-and-interferometry-techniques/ Wed, 19 Nov 2008 23:00:00 +0000 Roger Artigas
