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 varioSCAN can 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 aperture.
