About us

In cooperation with our strong partners such as “Kvant Laser (Slovakia)”, “Pangolin Laser (USA)”, the “TU Dortmund” and last but not least the “Fraunhofer Institute for Material Flow and Logistics in Dortmund”, we have been working on optimizing work processes with the help of state-of-the-art laser and LED technology since 2011. It is the know-how of “the whole team” that makes our work so successful.

At the beginning of 2023, we (GT-TECH Laser, a company for modern laser technology, founded on 01.03.2011) outsourced the industrial sector to a new company, Virtual Line GmbH. The “Virtual Line” division brings with it completely new possibilities for the projection of marking lines and warning signs, which the entire team is constantly researching, developing and improving with passion.

Initially, our focus was mainly on the further development of laser technology in order to be able to change the color and shape of projected floor markings – and above all – in real time. In the meantime, it has become clear that many floor markings can be static, which is why we are also intensively developing LED technology!

When it comes to laser safety, Virtual Line GmbH and GT-TECH Laser have been in regular contact with TÜV SÜD Industrie-Service for many years. We would particularly like to highlight the commitment of Dr. Günter Uhlig, who is always on hand to advise us as an expert.

Our customers include universities and research institutes as well as prestigious companies such as Carl Zeiss Jena and Siemens, to whom we have been providing both our latest lighting technology and our know-how for years. Even the Federal Minister of Labor, Hubertus Heil, has already taken a look at our technology.

The change of company from “GT-TECH LASER” to “Virtual Line GmbH” in 2023 will not be a problem for our customers, as the company headquarters, shareholders, contact persons and contact addresses will remain the same.
