Projects & Partners

LTB Lasertechnik Berlin GmbH has started the two-and-a-half-year PoSaLIBS project which aims to carry out fundamental research on a portable measuring system for rapid chemical material analysis using spark enhanced laser-induced plasma spectroscopy (LIBS). This project is co-funded by the European Union.
The LTB Lasertechnik Berlin GmbH is a proud member of the European consortium EURO-TITAN, which aims to explore innovative technologies to reuse metallurgical waste streams from titanium dioxide and aluminium production for titanium production. In this context, LTB is developing an in-situ LIBS measurement system for the direct chemical analysis of slag in the hot melt. The project is funded by the European Union.

LTB Lasertechnik Berlin GmbH prioritizes sustainability by operating a fleet consisting mainly of electric and hybrid vehicles. This commitment extends to their headquarters, where a rooftop solar system and a geothermal energy system with heat exchangers further minimize their CO2 footprint.

The purchase of these eco-friendly vehicles was supported with subsidies from the European Union’s NextGenerationEU initiative.
