Fixed optics that can be combined with the TruDiode
Programmable motor focusing

Thanks to motor positioning of the collimator lens, the focus point can be conveniently set in the Z direction. Modifications can be entered either directly via the laser control system TruControl or via an external machine control. Applications for which the focal position must be frequently changed can therefore be performed without a great deal of additional effort.

Protective glass and power measurement cassette
CCD camera

The CCD camera monitors the process at the processing point, and enables convenient setup of the laser process. It is the basis for process monitoring.

Protective glass and power measurement cassette
Protective glass and power measurement cassette

During operation and when changing the protective glass, the seal and interior ventilation of the protective glass prevent contamination. Changing the protective glass itself is quick and easy without tools. In place of the protective glass cassette, you can also insert a power measurement cassette. This enables you to easily check the laser power.

Crossjet option, TRUMPF focusing optics
Crossjet

Crossjet is a compressed air flow that runs orthogonally to the laser beam. It diverts contamination and spatter and thereby extends the service life of the protective glass. The optics become more robust and the laser process more reliable.

The metal vapour effect (MDE) nozzle stabilises the welding process.
MDE nozzle (metal vapour effect nozzle)

To make your welding process more efficient, you can add, in addition to the crossjet, the airflow from the metal vapour effect nozzle (MDE nozzle). The airflow keeps the metal vapour torch that arises while welding constant and therefore the energy brought into the material. This stabilises the welding depth for precise laser processing. You also reduce your costs through a longer service life for your protective glass.

Technology-Picture-laser-welding-machines
Shielding gas nozzle

For high-quality welding results, a separate nozzle supplies shielding gas. The welding seam thereby oxidises less. You can choose from various nozzles: aerator nozzle, linear nozzle or multiple pipe nozzle.

In addition to a range of processing optics, TRUMPF also offers you the right machines and beam sources to be used with these. This allows you to find exactly the right combination for your application and requirements – all from a single source. When it comes to beam sources, TRUMPF offers all industrially relevant lasers. You can rely on our experts, trust us to always have the best solution in mind for your production tasks and know that we will advise you independently of any preferred technologies.
