Description

Description
The Allegro 2411 thin-film structuring system is used to structure (subdivide) the coatings of float glass substrates with the aid of lasers during production for the manufacture of thin-film solar cells.
The processing is carried out from the top of the substrate with laser beams with a wavelength of 1064 nm. The distance between the laser beams, the laser power, the movement paths and focus positions of the laser as well as the associated workpiece data are determined via the software user interface
and can be saved as recipes and called up again.
