Successful on the market since 1869

Foundation of the optical and precision engineering workshop by Florenz Sartorius.
Takeover of the company by Louis Draeger.
Son Georg Draeger and son-in-law Friedrich Heerhorst join the company. Hence the name Dräger & Heerhorst Göttingen. The initials of the surnames and the city can still be found in our trademark/company logo today.
Conversion of the company into a limited partnership, which makes a name for itself worldwide with the manufacture and sale of medical devices and instruments. During this time, the nystagmus spectacles are developed in collaboration with Professor Hermann Frenzel.
Takeover of the company by long-time employees Kai Uwe Lach and Karl-Wilhelm Koch. The company continues to operate under the name DEHAG Medizin-Technische Produktions GmbH & Co KG.
After the retirement of Karl-Wilhelm Koch (2005), the company moved to its current production facility in Rosdorf in January 2008


If a new or relatively new device has defects, malfunctions or other errors, this is often a warranty case. The processing can then be correspondingly time-consuming and possibly also complicated. What about the guarantee, warranty and right of return, what claims can I make – money back, repair, replacement? These issues are often unclear – use our service.
If you have any questions about the warranty, please contact our customer service team, we will be happy to help you.


Individually we can make products according to your request. We offer reliable continuity and competence for production in small or even larger quantities. Contact us and we will show you the individual possibilities.


Despite high quality, it can happen that a medical device fails or that individual components wear out. To ensure that you can still continue your practice operations as usual, our technical customer service is available to you with fast and reliable all-round service in compliance with all legal requirements for repair, maintenance and testing. We offer short response times, high customer orientation and always technically optimal and economically most favorable solutions.
