The line-focusing optics IR from TRUMPF form a thin line from the standard round laser beam, and distribute the power intensity evenly over the entire line profile.Reqiest offer
Extremely narrow, extremely long, extremely even: Line-focusing optics from TRUMPF form a thin line from the round laser beam, and distribute the power intensity evenly over the entire line profile. If several line-focusing optics are combined in a modular manner, lasers with an infrared wavelength can even process large areas of several square meters. During the laser lift-off process used in the manufacture of modern OLED displays, the line-focusing optics focus the laser beam with an ultraviolet wavelength in a line shape from behind through the glass substrate. TRUMPF line-focusing optics can be flexibly combined with the pulsed and continuous-wave solid-state lasers from TRUMPF, and can be adapted precisely to spatial and application-specific requirements.
Together with Saint-Gobain and Manz, TRUMPF has developed a patented technology for the surface treatment (“rapid thermal annealing”) of industrially manufactured plate glass. In this so-called ACTILAZ™ process, a silver layer which is just a few micrometers thick is briefly heated up on the glass substrate. Twelve TRUMPF TruDisk disk lasers with an infrared wavelength connected in parallel, as well as eight IR line-focusing optics combined in a modular manner generate a laser line which is 3.3 m long and thinner than 100 µm over the entire width. The intensity of the laser radiation varies by less than 10% in the process.
The power intensity is distributed evenly over the entire line profile with fluctuations of less than 10%.
The line-focusing optics can be easily integrated in industrial production lines, and can be individually combined for every application.
With a width which is smaller than a human hair, the line-focusing optics focus the laser beam onto the workpiece with a high irradiance.
IR line-focusing optics can easily be combined in a modular manner so that laser lines of several meters can be created.
