Abstract: The invention relates to a system comprising: a source for generating a light beam (B), an optical element (M) intended to receive said light beam (B), an actuator (AC) in which is mounted a plurality of objective lenses (OL0, OL1 . . . ), translation means for translating said optical element (M) so as to direct said light beam (B) toward a given objective lens taken among said plurality of objective lenses (OL0, OL1 . . . ).

Abstract: The electronic device (1) has a layer (11) of a material comprising a first and a second element. This material has an amorphous and a crystalline state. A transition from the amorphous to the crystalline state can be effected by heating of the material to above a crystallization temperature, for example with a laser. As a result, the layer (11) has a first electrically conducting areas (21), comprising the material in the crystalline state, which are insulated from each other by the first electrically insulating area (23), comprising the material in the amorphous state. The layer (11) may be present as an interconnect layer, but also as a covering layer. Preferably, the material is aluminum-germanium. In the method of patterning a layer (11), electrically conductive areas of the layer can be strengthened by electroplating.
