In 1855 Kellner died at age 29 of tuberculosis his widow married Friedrich Belthle and secured the existence of the Optical Institute. Increased demand presented difficulties for Kellner, as the old-fashioned production techniques of his small workshop limited the number of microscopes that could be produced in the first five years in business only 130 were manufactured. As word spread about their high quality, demand grew. The institute manufactured three types of microscopes with a different number of lenses. Two years later there were more microscopes leaving the Optical Institute than telescopes. Because he designed them based on mathematical principles, they generated images of exceptionally high quality. Kellner's microscopes soon earned a reputation among scientists. The first microscope was delivered to Geneva, Switzerland, for testing in 1851. In his workshop in Wetzlar, which employed 12 assistants, Kellner started manufacturing microscopes. His invention was a success among scientists, and Kellner decided to use his knowledge to build a new kind of microscope. Specifically, Kellner invented an optical corrected eyepiece with a new combination of lenses that significantly improved the image quality in field glasses and telescopes. Kellner was very talented in detailed mechanics and interested in optical studies, to which he also applied his studies in mathematics.

In 1849, in the German town of Wetzlar, 23-year-old Carl Kellner founded his own Optical Institute. Another important business area are confocal microscopes based on laser technology which allows the creation and analysis of 3D images in clinical diagnostics, cytogenetics, and materials science. LMS is also among the world market leaders for automatic measurement and inspection systems for the inspection of microchips and wafers in the semiconductor industry. Light microscopy has been at the core of the LMS's business since the company's founding. About 90 percent of the company's sales are generated outside Germany, supported by 18 sales organizations and associated dealers around the world. LMS is based in Wetzlar, Germany, and produces a broad range of optical and opto-electronic instruments in 11 factories in Germany, Switzerland, Austria, England, the United States, China, and Singapore. Leica Microsystems Holdings GmbH (LMS) is one of the world's leading manufacturers of microscopes and related scientific equipment for research in the healthcare, semiconductor, and other industries. History of Leica Microsystems Holdings Gmb H Leica symbolizes not only tradition, but also innovation.

Germany: Hesse, Wetzlar Physical Description Ref: Ernst Leitz, Microscopes and Accessory Apparatus (Wetzlar, 1907), pp. The firm became Ernst Leitz Microscopes at that address in 1903, and moved to 411 W. Ludwig Leitz and William Krafft, both of Wetzlar, came to the United States in 1893, and Krafft began in business as a microscope importer at 30 E. This is a simple dissecting microscope with rack-and-pinion, moveable lens carrier, large glass stage, sub-stage mirror, and wooden case.
