Projects & Partners

The repetition rate and lifetime of a laser are key parameters especially with regard to a highly competitive market in the laser sector. Therefore nitrogen laser technology, particularly applied for MALDI-TOF and MALDI Imaging, needs to be reviewed to provide significantly higher repetition rates for increased application requirements. The project RAPTOR is funded by the European Regional Development Fund (EFRE) and aims to carry out fundamental research on high repetitive UV gas lasers.

LTB Lasertechnik Berlin is member of the Competence Network for Optical Technologies Berlin-Brandenburg.

Quality management

LTB Lasertechnik Berlin GmbH is certified according to DIN EN ISO 9001:2015 .

The introduced Quality Management System (QMS) shall ensure that development, production and sales of lasers, spectrometer and laser-based measuring systems meet our high demands for quality and efficiency. We seek a continuous improvement of our internal processes.






On July 6, 2017, LTB Lasertechnik Berlin has been awarded the prize for “most family-friendly company 2017” of Treptow-Köpenick, by mayor Oliver Igel. The award ceremony took place during the business cards meeting of the Economic Development Treptow-Köpenick in the “Späth´schen tree nurseries”. The competition has been held annually since 2005 and is announced by the District Office. Lasertechnik Berlin has been applied this year for the first time.

In February 2017, LTB Holding GmbH started an extension to its production and administration building, which was completed in 2013. The need for capacity expansion arose from the positive development of the two subsidiaries LTB Lasertechnik Berlin GmbH and Lufttechnik Schmeißer GmbH. The completion of the new building with a floor space of approx. 1,500 sqm is planned for November 2017.
