varioSCAN, varioSCANde i

Typical applications:   -. Drilling, cutting, welding  -. Laser deep engraving  -. Rapid prototyping, rapid tooling  -. Microstructuring  -. 3D workpiece processing

The dynamic focusing units of the varioSCAN and varioSCANde i series enable exceptionally precise, high-performance positioning of the laser focus along the optical axis.

In XY scan systems, the varioSCAN can replace costly flat field objectives. Therefore, the varioSCAN is an ideal solution in applications for which standard flat field objectives are unavailable. The varioSCANcan also extend XY scan systems into 3D beam deflection systems. The laser focus is guided along the contour of the workpiece being processed, thus enabling processing in three dimensions. The varioSCANFLEX additionally allows continuously adjusting the image field size, working distance and spot size.

The high-end member of the varioSCAN series of focusing units is the varioSCANde i. It is equipped with a digital linear encoder.

The varioSCANde i offers double the maximum travel of conventional varioSCANs and much lower tracking error, resulting in a larger focus-shift range and better spot quality. Its accuracy, speed, resolution and linearity, too, are clearly superior to those of all other varioSCAN units, while substantially eliminating the effects of drift.

In addition, the varioSCANde i delivers all advantages of iDRIVE® technology: extensive flexibility, high dynamic performance, realtime querying of actual position and other status parameters, etc.

The varioSCAN 40's integrated air and water cooling ensure operation at very high laser powers. The varioSCAN 20 can be optionally equipped with a water-cooled entrance

powerSCAN, powerSCAN i

Typical applications:   -. Laser processing of materials  -. Rapid manufacturing  -. 3D applications  -. Processing-on-the-fly

The scan systems of the powerSCAN series enable positioning multiple kilowatts of laser power onto a workpiece in just a few milliseconds. In combination with a varioSCAN, the laser beam can be dynamically focused within working volumes, thus allowing non-flat workpieces to be processed.

Apertures from 33 mm up to 70 mm allow small spot sizes and therefore high power densities even with large working distances.

The XY mirrors and the varioSCAN's optics are air cooled, while the scanners, electronics and varioSCAN are water cooled. This ensures reliable operation with excellent long-term stability - even under challenging environmental conditions and with high laser powers.

Each axis of the powerSCAN 50, 50i, 70 and 70i is individually implemented as a sealed submodule - a calibrated and tuned unit containing a galvanometer scanner with a mirror and the scanner's drive electronics. Thus, rapid replacement of individual axes is ensured. Located in a separate sealed base module, the modularly designed main electronics provide functions such as a digital interface and a power management system with comprehensive monitoring functions.

The powerSCAN i-series of scan systems employs the same iDRIVE® electronic concept used in the success-proven intelliSCAN®. This brings improved dynamics and advanced querying possibilities. The series includes both the powerSCAN 50i and powerSCAN 70i.

intelliWELD®

Typical applications:    -. Robot-assisted welding ("remote welding") -. 3D applications -. Processing-on-the-fly

Designed for robot-assisted welding applications, this 3D-scan system is capable of swiftly positioning the laser beam along 3D contours. While a robot guides the scan system along a part's contour, the intelliWELD® quickly and accurately moves and fine-positions the laser spot. Complex robotic motions and fast robotic repositioning are thereby avoided, thus reducing positioning times between spot welds to a few milliseconds. The result is substantially enhanced utilization of the laser source.

Despite its 30 mm aperture, the intelliWELD® occupies a remarkably small volume, making it easily mountable on welding robots, even in difficult-to-access locations. Its optics are optimized for fiber-coupled disk or fiber lasers with powers up to 8 kW.

The intelliWELD® incorporates SCANLAB's fully digital iDRIVE® technology, offering an integrated approach to laser and process safety. This allows real time monitoring of all important scan head status parameters. A software-independent interlock signal indicates abnormal operational states.
