Leica Camera AG, a German optics company, manufactures Leica cameras. The predecessor of the company, formerly known as Ernst Leitz GmbH, is now three companies: Leica Camera AG, Leica Geosystems AG, and Leica Microsystems GmbH, which manufacture cameras, geosurvey equipment, and microscopes, respectively. Leica Microsystems AG owns the Leica brand and licences the sister companies to use it. History Before WWII The first Leica prototypes were built by Oskar Barnack at Ernst Leitz Optische Werke, Wetzlar, in 1913. Intended as a compact camera for landscape photography, particularl...

Vertico-SMI is the fastest light microscope for the 3D analysis of complete cells in the nanometer range. It is based on two technologies developed in 1996, SMI and SPDM. The effective optical resolution of this optical nanoscope has reached the vicinity of 5 nm in 2D and 40 nm in 3D and is therefore substantially better than the physical limit of 200 nm predicted by Abbe‘s law. Abbe postulated in 1873 the theoretical limit of resolution of optical microscopy. The Vertico-SMI microscope was developed by Christoph Cremer, Professor of Applied Optics and Information Processin...
