R&D Projects

The scientific team of BBT – Materials Processing, Ltd. participated as a prime- or subcontractor in a series of technological contracts focused on the development of new optical and acousto-optical components for terrestrial and space use. These projects, often with international participants, have been supported by various governement or non-government institutions and support programs.
