ZEISS - an internationally leading technology enterprise operating in the fields of optics and optoelectronics. ZEISS solutions contribute to world optics development and technological progress. With our passion for excellence, we create value for our customers and inspire the world to see in new ways. The ZEISS Archives contain original documents, files, photos, patents, registered designs, product literature, technical documentation and instruments from more than years of company history. The Archives were established in This is where the rest of the written documentation was collected, documentation that survived WWII, the American confiscations and the Soviet dismantling of German industry. The Archives are open Monday to Friday from 9 a.

The mechanics from this early period come from all over Germany and some of them stay only for a short time.

The opticians, on the other hand, who were initially trained by Carl Zeiss itself, came from the region and usually stayed until the end of their professional lives. Search for employees until Another map illustrates where the microscopes were sent until Zeiss initially delivered more to German and Russian university towns, but later he also achieved great growth in the western european science and trade metropolises.

Research for microscopes until Chronicle of Optics In the early s, archivist Fritz Ortlepp put together a chronicle of optics. It consists of some 30, index cards and ranges from the pre-Socratic philosophers to about This card catalogue is currently being processed so that it can be made available as an online database. Virtual Museum The biographies of the most important Carl Zeiss employees up toincluding photos, are currently being compiled. They are being added to the Virtual Museum along with a photo.

There will be links to the instruments that each person invented. The patent database for the period before will also be included in the museum. The patents are to be linked to the inventors and products.

However, due to the diversity of companies and business units, this will take some time to complete. Parts of the Virtual Museum will be translated into English. Due to the volume of data involved, however, this will take some time.

Like on the internet, "full-text searches" are possible. However, it often turns up very imprecise results.

For this reason, there are three further ways of searching that are typical for archives:. Indices Keyword, device and place indexes enable precise searches for particular information. In general, the individual keyword is followed by a derivative and a comma in order to keep the number of hits at a reasonable level.

Therefore, it is advisable to also consider related terms in the index lists keywords, devices, etc.

The ZEISS Archives

Document Plan Since the mids, the document plan of the Ministry for Electronics and Electrical Engineering has been used. This file plan has its disadvantages. The content was arranged by topic and formal cts e.

The origin is not important. For instance, as per the document plan, "Workloads of the Different Management Levels" had to be filed under number 0.

The content was formally catalogued on the level below that Specifications, Designs, Protocols, Templates. There was no way to distinguish between the "different management levels" such as combine and enterprise management.

They can therefore not be distinguished here.

That's why this document plan is not suitable for all archive searches. However, as the documents were pre-classified in this way, this system remained in use.

Classification A completely new classification was created based on origin. An attempt was made to use the document origins as a guide to the greatest possible extent. Consistent division was not always meaningful, which is why, for example, the plant management documents, which could in theory be responsible for all questions and problems, are allocated to the respective directorates and departments.

There are 4 hierarchy levels: at the top is the inventory, and below it are the main departments and directorates, followed by the other departments. Large document volumes are allocated by tasks and responsibilities on the lowest level. The written records of Carl Zeiss Jena contain production and dispatch lists for microscopes and optical measuring instruments.

This means instrument specifications, production details and information about the recipient can now be researched online. The lists were compiled with old German handwriting, which means they are sometimes confusing and thus hard to work with. If you have any questions, please contact us. Microscope production lists production data and dispatch lists e. From this date onwards, only delivery data was collected. The lists are normally structured as follows:. In book 1, simple and compound microscopes appear in separate lists.

Simple microscopes were given their own numbers, from 1 toand compound microscopes from 1 to 5, In books 2 through 7, the microscopes are listed in numerical order, from 5, to 69, This does not apply to the dissecting microscopes, which are logged in book 3, and numbered from 10, to 51, The first simple microscope was sold inand from onward Carl Zeiss began to incorporate new design features the fixed stage and movable lens holder into his microscopes.

The first compound microscope was produced in The Roman numerals are used to indicate different stand sizes, rather than chronological order. It was possible to select different combinations of lens systems A, B, C and eyepieces 1, 2, 3, 4.

InErnst Abbe scheduled production of microscope optics based on optical laws and Otto Schott melting of new optical glass triggered a boost in microscope development. Inthe company celebrated the production of the 10,th Zeiss microscope. And inHenry Siedentopf and Richard Zsigmondy built the slit ultra-microscope, which ultimately earned Zsigmondy the Nobel Prize in Any ZEISS instruments that used optical methods to determine chemical or physical characteristics were referred to as measuring instruments.

This area also paved the way for the creation of other product groups like geodetic instruments, stereoscopy and photogrammetry. From and refractometer no. The instrument type should first be identified before research can be conducted into the production lists.

Carl Pulfrich began setting up the Optical Measuring Instruments field of the business. This was followed by the launch of the Pulfrich refractometer for chemists in Other product creations included butter refractometers and milk fat refractometers Pulfrich and Wollny.

InPulfrich developed the immersion refractometer for chemical and clinical laboratories; the photometer Pulfrich and interference measuring instrument Pulfrich came later. From onward, instruments for measuring length, refractometers, spectrometers, technical inferometers and colorimeters were advanced by Dr. Their scientific, technical and sociological development and importance popularly described.

Serial through are dated Your 80mm lens is somewhere prior to ' You can rest assured your lens is most likely was produced during or Based on the serial number your lens is the 6 element design 80mm. The 7 element design began production around Oct 6, Correction: I left out the last digit on the number stamped on the back of the lens: That doesn't fit into any of the blocks in the Nordin book I located one.

I'm wondering if the lens was so badly damaged that the factory assigned a new serial number when it was serviced? Maybe in ? The following is a shortened version of the one in "Chiffres Clef" with some extra notes added from experience here.

can believe

It is tentative in places. The earliest Zeiss Anastigmat noted so far is No1,51x suggesting a possible No start at Jena for camera lenses: but note an aplanat for projection seems anomalous.

This must have been one factor leading to a big expansion of demand and production. It is an anonymous item. Thus they are distinguished by quoting as M 3.

Now a plant of a successful company does not vary that much in production rate unless there is diversion to other products, as is likely during a war binoculars? Or there is a cessation of materials or labour, which can also happen in war. These will have affected things in say to but it does seem likely that the numbers used in are a "funny" and one feels they include some for as well.

all became

Also note that there are gaps between the "Years lens" numbers, as for No, in end and No, for begin, where 30, numbers are "missing. It seems likely that there was a carry over of numbers in some years from one year to the next, due to numbers being booked for a contract or sale in advance- or some such mechanism.

There is a instinctive feeling that inthe plant was actually normally making about 25, lenses.

reply, attribute

Now going backwards, it is likely that production had built up slowly as labour was trained and plant designed and built, and that a typical serial number for might be No40, as suggested aboverather than No75, which would be the mid-point from No to say No, in After WW1, there is a rapid recovery of production, but again there are big fluctuations in the apparent yearly numbers produced. There are also still gaps between the blocks of numbers attributed to years.

It does seem that production was set to rise steadily in the 's, even though there was a recession, and especially after the formation of Zeiss Ikon with the related rationalizations and a "captive" market. Thus bythere do seem to be someor more per year, and then in the 's, up toornumbers per year used. All this does also raise one point: that any maker quickly finds that while brass and glass cost money, numbers are "free" and makers often "waste" numbers when plans change or products are cancelled.

Thus it is normal to find cases where lenses were never made to match numbers reserved for them.
