Line-focusing optics IR

The perfect laser line for every application – thanks to the TRUMPF line-focusing optics

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 metres. During the laser lift-off process used in the manufacture of modern OLED displays, the line-focusing optics focus the laser beam with 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.

Even power distribution

The power intensity is distributed evenly over the entire line profile with fluctuations of less than 10%.

Simple integration

The line-focusing optics can be easily integrated in industrial production lines, and can be individually combined for every application.

Thin line, high irradiance

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.

Processing of a large area

IR line-focusing optics can easily be combined in a modular manner so that laser lines of several metres can be created.

Together with Manz and TRUMPF, Saint-Gobain has developed a patented technology for the surface treatment of industrially manufactured plate glass in the form of ACTILAZ TM. TRUMPF line-focusing optics form a homogenous laser line which is 3.3 m long for this. This video shows how this works in practice.

Architectural glass

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 micrometres 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.

Remote Services

In the event of a fault, TRUMPF service experts will remotely access your laser via a secure remote connection. In many cases the fault can be remedied directly in this way, or the configuration of the laser can be modified in a way that permits you to continue manufacturing until the spare part arrives. This enables maximum availability for you.

Cooling processing optics/optical laser cables

Processing optics and optical laser cables can be cooled easily and conveniently using the laser cooling water. Separate cooling is therefore not necessary.
