Zeiss
The Carl Zeiss AG is a German manufacturer of optical systems, industrial measurements and medical devices, located in Oberkochen with important subsidiaries in Aalen and Jena. Carl Zeiss is the premier company of the Zeiss Gruppe, one of the two large divisions of the Carl Zeiss Foundation. The Zeiss Gruppe is located in Heidenheim and Jena.
The organization is named after its founder, the German optician Carl Zeiss (1816-1888).
The other division of the Carl Zeiss Foundation, Schott Glass AG, is located in Mainz.
Zeiss Ikon history
The history of Carl Zeiss AG begins in Jena before World War II, then the world's largest location of camera production. Zeiss Ikon represented a significant part of the production along with dozens of other brands and factories.
The destruction of the war caused many companies to divide into smaller subcompanies and others to merge together. Nevertheless, there was an enormous amount of respect for the innovation and engineering that came out of Dresden—before the war, Dresden had been responsible for the world's first SLR camera (the ''Kine Exaktra'') and the first miniature camera with good picture quality.
After the war, Zeiss moved to Oberkochen (in southwestern Germany), and Braunschweig.
Following the total economic collapse after the German reunification, Zeiss has returned to the marketplace. Since the 1990s the companies of the Zeiss Gruppe in and around Dresden have branched into new technologies: 3D-LCD screens and products for the automotive industry, for example. Zeiss nonetheless still continues to be a camera manufacturer, and still produces the ''Pentacon'', ''Praktica''http://www.praktica.de, and special-use lenses (e.g., ''Exakta''). Zeiss also owns the ''Contax'' brand and produces other international brands.
Zeiss also produces lenses for space projects.
Today, there are arguably three companies with primarily Zeiss Ikon heritage: ''Zeiss Germany'', the Finnish/Swedish

: It looks pretty obvious that this was ripped straight from the site. Nevertheless, the content was very offtopic and, in areas, completely unreadable. I reworked all the other text on the page and couldn't find anywhere to stash the list, so it's been removed. I have, however, added an external link to the site you mentioned. --Milkmandan 03:08, 2004 Dec 22 (UTC)
microscope lenses
I saw nothing regarding Zeiss AG microscopes... maybe this could be included..
Zeiss Tessar
pl:Tessar
The Zeiss Tessar is a famous photographic lens design conceived by Paul Rudolph in 1902.
The name Tessar derived from the Greek word tetra to indicate the typical four lenses scheme.
The Tessar is an evolution of the Cooke Triplet design in which the rear element is replaced by a cemented achromatic doublet.
A Tessar comprises four elements in three groups, one positive crown glass element on the front, one negative flint glass element at the center and a negative flint glass element cemented with a positive crown glass element at the rear.

Carl Zeiss
Carl Zeiss (September 11, 1816 – December 3, 1888) was an optician commonly known for the company he founded, Zeiss. Zeiss himself also made a few contributions to lens manufacturing that have aided the modern production of lenses. Raised in Weimar Germany, he became a notable lens maker in the 1840's when he created high quality lenses that were "wide open", or in other words, had a very large aperture range that allowed for very clear images. He did this in the city of Jena at a self opened workshop, where he started his lens making career. At first his lenses were only used in the production of microscopes but when cameras were invented, his company (Zeiss) began manufacturing high quality lenses for cameras. He died on December 3, 1888 in Jena Germany, the very place that he began his life of lenses.
Youth
Zeiss began his life in Weimar, Germany where he went to a grammar school, and undertook apprenticeship under Dr. Friedrich Körne, mechanic and supplier to the court. He later attended lectures in math, experimental physics, anthropology, mineralogy and optics at Jena University. After seven years he opened a small workshop by himself with hardly any tools. He made many lenses but had little recognition until 1847 when he hired his first apprentice. The very same year his former master, Dr. Körne died, inspiring Zeiss to devote his life to working in the area of microscopes.
His Life
In 1847 Carl Zeiss started making microscopes full-time. His first innovation was making simpler microscopes that only used one lens, and were therefore only intended for dissecting work. He sold around 23 of them in his first year of production. He soon decided that he needed a new challenge so he began making compound microscopes. He first created the Stand I which went to market in 1857.
In 1861 he was awarded a gold medal at the Thuringain Industrial Exhibition for his designs. They were considered to be among the best scientific instruments
LSM (Zeiss)
''LSM'' is a line of confocal laser scanning microscopes produced by the Zeiss company. As of 2005, the state of the art is the 5th generation, including the LSM 510, LSM 5 Pascal, and LSM 5 Live.
LSM models produce a file format with the filename extension ".lsm". There are different generations of this file format depending on the generation of the microscope model, but all are essentially extensions of the TIFF multiple image stack file format.
File format details
These are technical details intended for use by scientists trying to write code to read LSM files.
At least in the 5th generation LSM format, important extensions to the normal TIFF format are:
# An additional set of image directory entries (IFD entries are a standard part of the TIFF format that normally describe the individual images in a stack) starting at byte 8 of the file, after the standard TIFF header. This directory is mostly redundant with the standard TIFF image property directories that are included with the individual image data. One important special entry in this directory is the entry with tag code 34412, which provides the byte address within the file for an additional set of headers.
# The additional set of headers pointed to by IFD entry 34412 includes more redundant information about the image files. More importantly, it includes byte address offsets for a number of important data blocks within the file.
# One offset address provided in the additional headers is the location of the "scaninfo" directory. The scaninfo directory is a long series of entries organized in hierarchical subgroups providing most of the relevant settings used for the scanning run. The scaninfo directory is dynamic in length; it includes metadata entries that indicate what level of the hierarchy is being traversed. The end of the directory is reached when the metadata entries indicate traversal backwards past the "root" level of the hierarchy.
