Laser-based optical microphone technology.

XARION Laser Acoustics announced the completion of its Series A round of financing with a seven-digit investment volume. XARION succeeded in winning the newly-founded TRUMPF Venture as the largest investor. As a result, the TRUMPF venture capital company is now placing its first investment. In addition to TRUMPF Venture, the circle of investors also includes Hans-Peter Porsche.

XARION develops and produces the world’s first laser-based optical microphone, enabling the measurement of ultrasonic waves in the air or in liquids. Its use will be instrumental in the development of fields such as non-destructive material testing, process control in industrial environments and medical diagnostics.

“Our membrane-less laser sensors can be used profitably in a whole range of industrial applications. Crucially important here is the ten-fold frequency range compared to state-of-the-art acoustic sensors,” said Balthasar Fischer, CEO of XARION Laser Acoustics, describing his company’s field of technology.

The investment underlines XARION’s and TRUMPF’s joint intention to work together closely on the use of optical sensors in industrial process monitoring. The technological proximity of TRUMPF, and its deep roots in industry, offer good opportunities for the further development and growth of XARION. “With these unprecedented opportunities in process monitoring, XARION is a key contributor to further quality increases and new applications in the Industry 4.0 environment,” said Christof Siebert, Head of Technology Management at TRUMPF, describing the background of the investment.

In 2016, after several years of development, XARION successfully entered the market. In addition to various high-precision sensors, it also supplies the necessary software for data analysis.
