Laforet, PhD James DeRose https://www.leica-microsystems.com/19022 Optical Coherence Tomography Surgical Microscopy What is OCT and how can it help ophthalmologists acquire high resolution information on ocular tissue? Optical Coherence Tomography (OCT) is a non-invasive, non-contact imaging modality used to visualize and monitor changes to the morphology of biological tissue. OCT employs low-coherence interferometry to create cross-sectional images that reveal sub-surface details of the tissues of interest. In the most common ophthalmic applications OCT systems use near-infrared light to generate high-resolution, volumetric images of tissue microstructures including the cornea, iris, crystalline lens, vitreous and retina. These images can enhance insight into pathological conditions such as glaucoma, age-related macular degeneration or diabetic retinopathy. https://www.leica-microsystems.com//science-lab/what-is-oct-and-how-can-it-help-ophthalmologists-acquire-high-resolution-information-on-ocular-tissue/ Thu, 01 Dec 2016 14:44:00 +0000 George Wildeman, PhD Hafeez Dhalla https://www.leica-microsystems.com/17418 Surface Metrology Optical Coherence Tomography A Healthy Dose of Interferometry Although interferometry may once have been dismissed by the medical community because of its inability to see inside the human body, its application within the wider biomedical arena is continuing to grow and evolve; so much so that the technique is now used in the production of prosthetic limbs, research in dentistry and even for cultivating stem cells. https://www.leica-microsystems.com//science-lab/a-healthy-dose-of-interferometry/ Thu, 14 Jan 2016 15:06:00 +0000 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/13385 Surface Metrology 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. 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/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/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
