Abstract
Based on the development of an adhering and solderable layer system microoptical subsystems are joined by laser beam soldering. Fluxless processing with AuSn - solder (80/20 weight%) results in joints that are stable, leak-proof and that contain low mechanical stress. REM - investigations show that the joining area is homogenous. The paper will discuss a number of industrial applications.
