The A.KRÜSS Optronic GmbH is a German manufacturer and distributor of optical and electronic measurement and analysis equipment and instruments for the Gemology (gemmology) based in Hamburg . The company is owner-managed and is one of the traditional Hamburg family businesses. It goes back to the optical workshop of Mechanicus Opticus Edmund Gabory, founded in 1796.
A.KRÜSS Optronic has agencies in 128 countries and provides training in commercial professions.
Company history
A.KRÜSS Optronic goes back to the optical workshop founded in 1796 by the mechanic and optician Edmund Gabory from Strasbourg. His colleague and son-in-law Andres Krüss opened his own company in 1844, which he called A. Krüss Optical Institute and in which he sold nautical instruments and nautical charts. In 1859 Edmund Johann Krüss, son of Andres Krüss, expanded the company to include a lens grinding shop and from then on produced photographic lenses, microscopes and projection devices, so-called fog imaging devices. In 1865 Krüss had his world-famous “ Laterna Magica ”, a forerunner of the film projector, patented. The company's products were awarded a Grand Prix at many international trade fairs, for example at the world exhibitions in Paris (1855), London (1862), Chicago (1893), Paris (1900), Saint Louis (1904) and Brussels in 1910.
In 1886 the two companies, which had been working separately until then, merged into one company. From 1888 to 1920 the company was headed by Hugo Krüss , who did pioneering work in the field of theoretical and practical photometry. His handbook of electrotechnical photometry becomes the basis of this subject. He transformed the company from a manufacturer of scientific instruments to an innovative scientific company and technological pacemaker that set standards in its field. As chairman of the German Society for Precision Mechanics and Optics, Hugo Krüss also campaigned for this branch of industry in politics. The Hamburg Senate appointed him professor in 1917, and the following year he received an honorary doctorate from the University of Göttingen . Hugo Krüss died in 1925 at the age of 72. Five years after his death, the Free and Hanseatic City of Hamburg honored him by dedicating a street in the Barmbek district.
Hugo's son, Dr. Paul Krüss, joined the company in 1904 at the age of only 24 and continued his father's work. As a “master craftsman with a doctoral hat”, he developed physical measuring methods and also constructed the necessary equipment. Paul Krüss led the company through the stormy times of the 20th century. After the Second World War, he handed over the management to his son Andres, who was able to win new customers from all over the world during the economic miracle. The continuity in the company's management was maintained through the 20th century. Martina Krüss-Leibrock has been running the company in the seventh generation since 1980. In 2005 her daughter Karin Leibrock also joined the company, so that the company has now been run by the family for eight generations. At the beginning of 2009, A.KRÜSS Optronic moved into its new company building near Hamburg Airport.
In 2013 Thomas Schmauck joins the management team and will be responsible for the operational business together with Karin Leibrock.
Products
Microscopes
Microscopes are traditionally part of the core range of A.KRÜSS Optronic. The company offers a wide range of stereoscopic and monocular microscopes that are designed for use in medicine, biology and technology. A wide range of accessories, such as cameras, light sources, lenses, etc. is available for this purpose.
Polarimeter
A.KRÜSS Optronic supplies polarimeters for determining the optical activity of substances from the robust, manually operated laboratory instrument to the fully automatic instruments of the PS 8000 series. The digital polarimeters of the P8000 series use a measuring process patented by Krüss that reduces the measuring time to one second, regardless of the angle of rotation.
Refractometer
A.KRÜSS Optronic offers refractometers for determining the refractive index of liquids and polymers both as stationary laboratory devices and as fully electronic mobile handheld devices. The devices can be used universally in food production and chemical engineering.
Further products
In addition, A.KRÜSS Optronic offers a wide range of other laboratory and analysis devices, such as
- Flame photometer
- Density meters
- Melting point meters
- spectrometer
- Gas analyzers
- Circulation thermostats
- UV and analysis lamps
- Cold light sources
- Laboratory software
Gemology
A specialty of A.KRÜSS Optronic is the range of gemological instruments. It ranges from gemstone refractometers and spectrometers to gemological microscopes and magnifying glasses to complete workstations and mobile suitcase laboratories, with which quality tests and analyzes can be carried out on site.
