The world's smartest polygon scanner

What is a polygon scanner?

In contrast to the galvo scanner with an oscillating mirror, the laser beam deflection in the polygon scanner is handled by a rapidly rotating wheel with several successively acting mirror surfaces. Since the seventies, this technology has shown its efficiency in laser printers.

LIDAR systems also use this interesting technique. The fast rotating wheel leads to an extremely fast deflection of the laser radiation. Depending on the number of mirror surfaces per wheel and the number of revolutions, a certain line frequency results.

The angular velocity of the beam is thus fixed. Depending on the focal length of the optics used, a certain deflection width results and thus a certain deflection speed. The optics thus determine the minimum focus size and the maximum deflection speed.

With the polygon scanner, the entire scan line is always scanned. This is advantageous for large-area irradiation. If only individual areas of a larger surface are to be irradiated, the polygon scanner is rather unsuitable. Due to the edges in the polygon wheel, at which the laser beam must be switched off, the polygon scanner achieves only a certain maximum degree of utilization.

The larger the usable beam diameter in relation to the mirror length, the smaller the degree of utilization for the laser. This can be compensated by a special control option for the laser (burst) or by using 2 parallel laser beams (USP laser).

Polygon scanners are not yet used that often in materials processing. This is also due to the fact that the laser powers to be implemented so far did not necessarily require the ultra-fast deflection. But the available laser powers are continuously increasing!

In the ns range as well as in the UKP range, previous scanning technologies are already reaching their limits. And for the use of low-cost cw lasers, polygon scanners open up completely new fields of application such as ablation cutting, polishing and cleaning. With a fast external beam circuit, it is even possible to perform high-resolution structuring.

So the time of the polygon scanner has just begun. If you want to work not only at 30 m/s but rather at 300 m/s and have the necessary laser power for your process, you should think about polygon scanners. MOEWE is the ideal partner with innovative and smart technology.

Unique functionality

Patented design and real-time data processing

Double reflection eliminates the fluctuations of the reflection point as a fundamental problem of polygon mirrors. In connection with a time marker and an extremely fast correction of manufacturing tolerances by an integrated FPGA (200 MHz) the polygon scanner system of MOEWE is extremely accurate.

• Patented special optical design for minimal distortion
• Patented real-time data processing through FPGA

For optimal results

Large clear aperture

The free aperture of 30 mm, which is extremely large for a compact polygon scanner with a mass of only 13 kg, allows the use of large laser beam diameters. Thus, very small focus diameters can be achieved. With a focal length of 270 mm, approx. 25 µm are obtained for a single-mode fiber laser in the NIR wavelength range at a scan length of 160 mm. Due to the large beam diameter and because all reflective surfaces only come into contact with moving beams, extremely high laser powers of > 5 kW can be deflected with the MOEWE polygon scanner. With a long focal length of 1,900 mm, scanning lengths of 1,500 mm can be achieved. The focus diameter is then still about 180 µm.

• Size: 30 mm
• Smallest focus spot diameter < 10 µm
• Suitable for high power lasers > 5 KW

Incredibly fast

Scanning speed > 1,000 m/s possible

The scanning speed of polygon scanners is about 30 times higher than that of galvo scanners. With a focal length of 420 mm our MOEWE polygon scanner system reaches a speed of 1,000 m/s at a line frequency of 1,300 Hz. Especially for raster processing, which is necessary anyway, and for continuous area irradiation, the benefit of a polygon scanner is obvious. With the increasing power of ultra-short pulse lasers, ultra-fast beam deflection with polygon scanners is useful to achieve the high productivity that such lasers allow, even at high quality. USP lasers with a single pulse frequency of > 10 MHz can still be precisely controlled with our device. In the laboratory the MOEWE polygon scanner system has already controlled a laser with  60 MHz. This leads to extremely fast machining processes.

• Significant time saving
• Efficient cost reduction
• Larger production volumes

MOEWE sponsors the event “12th International Summer School

From August 28 to September 1, 2023, the TU Dresden and the Fraunhofer IWS will host the 12th International Summer School on Laser Technology. In this five-day workshop, undergraduate and graduate students will be trained in fundamental and applied aspects of laser technology. The program includes lectures by experts, discussion sessions, practical insights and the opportunity for participants to present their own research topics and exchange ideas. We are very pleased to support this event as a sponsor. Dr. Florian Rößler, our research and development associate, gave a presentation on our polygon scanner at the site on August 30, 2023.






New speed record in laser cleaning

IPG Laser GmbH is a manufacturer of cleaning lasers. These have an enormously high pulse power of greater than one megawatt and a square process spot. Often they are guided by hand. On the initiative of MOEWE, IPG has now for the first time realized such a laser with a power of 6 / 3 kW and tailored it to the requirements of a fast polygon scanner. In particular, a special burst regime allows the entire laser beam power of 3 kW to be used in the process, which is otherwise not possible. With the PM 100, MOEWE is the only company worldwide to offer a polygon scanner for such a high laser power. SITA Messtechnik GmbH can demonstrate the cleaning effect with its measuring device.
