Online research can be done to prepare for, but not replace, a visit to the archives, since the file contents themselves cannot be uploaded to the internet.

To order files from the archives, you need the digital signature of each file. In our Virtual Museum, you can find every instrument manufactured by Carl Zeiss up to The devices have the original texts from the old brochures. Online research in the Virtual Museum. Exact manufacturing dates are often difficult to ascertain, which is why we have decided not to offer specific information.

A collection of roughly 1, Carl Zeiss instruments is on display in Jena. The items are lent out for company presentations to museums and to exhibition organizers. This collection builds on the collection from the former plant for optical precision instruments G-Plant at Carl Zeiss German Democratic Republic.

It has grown in the past few years. The aim is to collect these instruments, which document the product history and scientific development of Carl Zeiss in Jena. This is what distinguishes our collection from that of the optical museum in Jena and Oberkochen:. Today the two organizations are no longer directly linked. The Optical Museum documents the history of optics. The focus is largely, but not exclusively, on Carl Zeiss. Optical Museum. Short biographies are available for all employees who were hired until You can search by name, place of origin or profession.

The places of birth are shown on a map. 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. 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.

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 to , including 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.

If you are interested in taking part in one of the projects on a voluntary basis, please send an email to: wolfgang. 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. 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 aspects 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. In collaboration with the Thuringian State and University Library in Jena, digital scans of these books were published online to enable independent research.

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 to , and compound microscopes from 1 to 5, From 1, to 1,, the microscope stands featured two labels: stand no. 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, 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.

You can also contact us. The book Astro 1 documents serial numbers for different astronomical devices such as monocular and binocular telescopes, from no. It also includes information about accessories such as mounts, astronomical cameras, clock drives Uhrgan and domes.

In only 3 devices were assigned: numbers 50, through 50, A separate list details planetariums, from no. Unfortunately, there are no details about customers or delivery locations.
