NanoFocus AG becomes a wholly-owned subsidiary of the Mahr Group
On November 12, 2025, Mahr GmbH acquired the last three percent of shares in NanoFocus AG, making it its sole owner. The aim of the measurement technology specialist is to expand further with dimensional optical measurement technology.
With the acquisition of NanoFocus AG, the Mahr Group intends to expand further with dimensional optical metrology and thus become an important partner for quality assurance in many areas of industry. Optical metrology is a technology with great potential for Mahr. Thanks to its high speed, precision and non-contact measuring processes, it is increasingly establishing itself as an important alternative to tactile measuring technology. It is becoming increasingly important in many sectors: in medical technology, the automotive industry, mechanical and plant engineering and precision parts manufacturing. It is also used in aerospace technology, the defense industry and the electronics and semiconductor industries.
