Versatile optics for beam formation when cutting glass, welding transparent materials and soldering galvanized sheet metal parts.

Optics for beam formation when cutting glass

You are optimally equipped for every laser processing task with our beam formation elements of the TOP product group. Whether it is for cutting glass, welding transparent materials or soldering galvanized sheet metal parts – TOP Cleave, TOP Cleave-2, TOP Weld and TOP Braze will all win you over thanks to a very high processing quality and speed for a variety of materials. If necessary, we will develop a solution for beam formation that is suitable for your requirements.

High-quality seams

Welding with TOP Weld generates highly transparent seams. The high level of tightness makes it possible to encapsulate fluids or gases.

Effective welding

Thanks to the fact that there are no complex process steps or additional materials, you will protect your resources and your budget with the TOP product group.

Excellent edge quality

Benefit from quick cutting with TOP Cleave-2, which requires basically no post-processing.

Everything from a single source

Laser, processing head, optics, beam formation – we have everything in our portfolio at TRUMPF, perfectly coordinated for your requirements.

Soldering with TOP Braze
Reliable cutting of glass with TOP Cleave optics
High reliability

The compact, encapsulated housing of the TOP Cleave and TOP Cleave-2 focusing optics can withstand an acceleration of up to 2g.

High-speed processing with the TOP Cleave cutting optics from TRUMPF
Breakneck speed

The TOP Cleave focusing optics distributes the intensity of the laser light along the beam axis. The focus is lengthened. The laser pulses modify the entire interior cutting surface of a pane that is 0.04 in. thick, for example, in a single pass. With the high-performance lasers in the TruMicro Series 5000, you can attain a cutting speed of more than 39.4 in/s, depending on the material and geometry – more than one hundred times faster than without TOP Cleave.

Highly precise processing of glass

Very thin, hardened glass can be optimally processed with TOP Cleave-2. Depending on the pulse energy, the laser pulses modify the entire interior cutting surface of a pane that is 700 µm thick, for example, in a single pass.

Brazing in body construction

Whether it is for a roof seam or a trunk lid – the TOP Braze focusing optics make it possible to braze hot-dip galvanized metal sheets with in-situ pre-treatment by the processing laser.

High-speed laser cutting of glass

High edge quality

When cutting with TOP Cleave, you attain outstanding edge quality, and rework in the form of regrinding or polishing can be minimized or eliminated. Therefore, process duration and costs are significantly reduced.

Flexible geometries for laser cutting of glass

Any contour and the smallest geometries

With TOP Cleave focusing optics you can freely and precisely cut contours down to a hundredth of a millimeter. With extremely short laser pulses, you can modify a narrow area along any desired separating line. The change creates an intrinsic weakening, and the glass will break off in a controlled manner and as smooth as a mirror at the desired location.

Connecting transparent materials or transparent materials with opaque materials

With the TOP Weld focusing optics, you can connect transparent materials (for example, glass with glass) or transparent materials with opaque materials (for example, glass with metal) without intermediate layers. The material properties do not have to be matched to each other. The focusing optics distribute the laser energy along the joining zone, specific to the situation, while focusing position tolerances can be maximized.

Glass welding with TruMicro and TOP Weld

Thanks to TOP Weld, it is possible to weld materials in an industrial environment with permanent high stability. Moreover, the weld seams are water- and gas-tight.

TOP Cleave

The TOP Cleave and TOP Cleave-2 focusing optics are processing optics for quick cutting of transparent materials such as glass or sapphire. As a result of its patented technology, this process is substantially more effective, precise, and quick than ablative processes. In addition, the surface roughness is so minimal when cutting glass with TOP Cleave and TOP Cleave-2 that there is no costly post-processing.

TOP Cleave-2

With TOP Cleave-2 you can save on individual process steps because the large panes can be coated directly and separation can be carried out subsequently. In particular, very thin, hardened glass can be processed in the best possible way. The focusing optics for highly dynamic cutting distribute the intensity of the laser light along the beam axis which lengthens the focus. Depending on the pulse energy, the laser pulses modify the entire interior cutting surface of a pane that is 700 µm thick, for example, in a single pass. You can achieve cutting speeds of up to 1000 mm/s with the TruMicro Series; TOP Cleave-2 ensures outstanding edge quality.

TOP Weld

TOP Weld is the first processing optics for welding transparent materials or transparent to opaque materials (for example, glass to metal) without intermediate layers. It has never been possible before to weld materials in an industrial environment with permanent high strength. The material properties do not have to be matched to each other. The focusing optics distribute the laser energy along the joining zone, specific to the situation, while focusing position tolerances can be maximized. Compared to existing methods, larger gaps can be bridged, up to 10 µm.

TRUMPF-TOP_Braze

TOP Braze

TOP Braze makes it possible to braze galvanized metal sheets or aluminum components in body construction without spatter or pores, for example for roof seams and trunk lids. These different materials can be processed consistently and over a large area at high processing speeds of over 4 m/min. The result: smooth surfaces and sharp edges. You receive the complete solution from TRUMPF, all from one source, with the TruDisk Series, optical laser cable and processing head with beam formation optics.

In addition to a range of processing optics, TRUMPF also offers you the right beam sources for 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 relevant lasers for the industry. You can rely on our experts and put your trust in us. We always have the best solution in mind for your production tasks and we will advise you independently of any preferred technologies.
