NanoFocus AG Becomes Wholly Owned Subsidiary of Mahr Group
Mahr GmbH has announced that it has acquired the remaining three percent of shares in NanoFocus AG in Oberhausen becoming its sole owner. The goal of the metrology specialist is to continue expanding with dimensional optical metrology and thus be a very relevant partner for quality assurance in many areas of industry.
The focus will be on high-precision tactile and optical measuring systems that can be seamlessly integrated into modern Industry 4.0 manufacturing environments, thereby making a decisive contribution to increasing productivity, quality, and overall equipment effectiveness (OEE).
Optical metrology is a technology with great potential for Mahr. Due to its high speed, precision, and non-contact measurement processes, it is increasingly establishing itself as an important alternative to tactile metrology. It is becoming increasingly significant in many industries, such as medical technology, the automotive industry, mechanical and plant engineering, precision parts manufacturing, aerospace technology, the defense industry, and the electronics and semiconductor industries.
“The optical metrology of our brand NanoFocus perfectly enhances our expertise – following the acquisition of OptoSurf GmbH in 2024 – and solidifies our position as a leading provider in dimensional manufacturing metrology,” comments Manuel Hüsken, CEO and Chairman of the Management Board of the Carl-Mahr Group.
All minority shareholders of NanoFocus AG have been compensated, and trading of the shares on the Munich and Berlin stock exchanges was discontinued as of December 22, 2025.
