The Dr. Johannes Heidenhain GmbH , often just Heidenhain ( own spelling in capital letters), is a German manufacturer of mechatronic measuring devices for length and angle based in Traunreut in Upper Bavaria ; also be CNC controllers manufactured. The length and angle measuring systems are suitable e.g. B. for use in automated machines and systems, especially for machine tools .

The company has its origins in a metal etching shop founded by Wilhelm Heidenhain in Berlin in 1889. In addition to stencils, company and name plates, the company also made scales. In 1928, the Metallur process was developed at Heidenhain and a patent was applied for. This lead sulfide copying process made it possible for the first time to copy an original graduation exactly onto a metal surface and could be used industrially. The company owner Wilhelm Heidenhain died in 1932 and his son Johannes Heidenhain (1898–1980), who had been Otto Hahn's partner and former employee since 1929 , took over management of the company. In 1943 Heidenhain manufactured length rulers with a deviation of ± 15  µm and circular dividing disks with a deviation of ± 1 arc second. Today Heidenhain manufactures linear scales with measuring steps of 0.005  µm .

After the Second World War, Heidenhain was founded (entry in the commercial register on January 1, 1947), initially with its registered office in Rain am Lech , but moved to Traunreut in 1948 . The invention of the Diadur process made it possible to apply very fine structures made of chromium to any substrate such as B. to apply glass. Heidenhain used this for the production of price-indicating scale scales or writing discs. The DIADUR process was patented on February 28, 1950. Based on the Diadur process, optical position measuring devices for machine tools were added to the range in 1952. In 1961 photoelectrically scanned linear and angle encoders followed. In 1968, numerical position displays were produced for the first time.

In 1970 the non-profit Dr. Johannes Heidenhain Foundation GmbH founded. The Dr. Johannes Heidenhain GmbH is 100% owned by the foundation.

In 1976 the first Heidenhain CNC control was developed. In 1987, a length scale with an interferential measuring principle was introduced in series , which enables measuring steps down to one nanometer . In 1997, the EnDAT interface was created, a fast serial data channel for the transmission of position information.
