    Highly dynamic cutting of transparent materials without post-processing

    The TOP Cleave focusing optics are processing optics for quickly cutting 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 that no costly post-processing is necessary.

    Breakneck speed

    With TOP Cleave optics you can achieve process speeds of > 1 m/s.

    Cutting thick glass

    You can cut glass thicknesses of more than three millimetres in just one pass.

    No post-processing

    Straight slitting edges with a surface roughness of less than 1 µm save on time-consuming post-processing.

    Breakneck speed

    The TOP Cleave focusing optics distribute the intensity of the laser light along the beam axis. The focus is lengthened. Depending on the pulse energy, the laser pulses modify the entire interior cutting surface of a pane that is 1 mm 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 1000 mm/s, depending on the material and geometry – more than one hundred times faster than without TOP Cleave.

    Cutting glass with TOP Cleave

    A typical application for the TOP Cleave cutting optics is the processing of thin, hard display glass for smartphones. In the past, thermally or chemically toughened glass was cut into defined sizes, loaded onto carriers, and then coated. With TOP Cleave you can save on individual process steps because the large panes can be coated directly and the individual pieces of glass can then be cut out later on.

    High edge quality

    When cutting with TOP Cleave, you attain outstanding edge quality, and reworking in the form of regrinding or polishing can be minimised or eliminated. You thereby significantly reduce the duration of the process and the processing costs.

    Flexible geometries for laser cutting of glass

    Any contours and the smallest geometries

    With TOP Cleave focusing optics you can freely and precisely cut contours down to a hundredth of a millimetre. 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 smoothly and in a controlled manner at the desired location.
