Klaus Eckerl

Dipl.-Ing. Mechatronics

CEO / President

Senior Optic Designer

Klaus studied mechatronics in Nürnberg, Germany and completed his studies successfully in 1988 as a diploma engineer. He worked on software and hardware development on stepper motor units as a free engineer. Employment in the optical industry followed as technical director at ENNA WERK, Munich with approximately 300 employees. During that time he worked in the field of projection, zoom lens design and production as well as working on plastic molding for slide projectors. Klaus  worked in the field of design and development of optical coatings with Leybold systems. He did optic design and quality engineering on projection and zoom systems for well-known companies like Schneider Kreuznach, Kodak, Docter Optics, Zeiss Oberkochen and Jenoptik. He worked on opto-mechanical design on Inventor professional software. Finally, he was  responsible for the quality management for all key account customers. Later, Klaus established the new field of industrial optics at ENNA. He was responsible for engineering und production of customized systems in glas and plastic. 
After ENNA was sold to Docter Optics in 1992, Klaus decided to start his own company, IB/E, short for  „Engineering Bureau Eckerl“. Since 2001 he has been managing director at his own production company IB/E Optics GmbH. In 2012, he finally fulfilled another dream of himself by moving into his self-designed IB/E headquarters in Freyung.
