Polygon Scanner Systems Galvanometers for additional flexibility / accuracy USP-Laser (optional other laser) Laser control Application paired f-theta optics High-speed scanner for line-by-line processing For ultra-precise micromachining of diverse materials ultra-short pulse (USP) lasers are the best choice, because cold ablation allows particularly fine, targeted material removal. To achieve industrialscale productivity, USP lasers must be combined with ultra-fast scanners like a polygon scanner system. Polygon scanners are particularly advantageous for line-oriented full-surface processing of workpieces and surfaces. Through the high speed, these systems can drastically reduce material processing times. USP laser processing applications range from structuring touchscreen surfaces or solar cells, to micro-drilling and processing of electronic components, glass and plastics, as well as sensor manufacturing. SCANLAB together with its subsidiary Next Scan Technology offers a wide range of polygon scanner systems allowing application specific customization for optimum efficiency. Axis position Mechanical axis High Throughput Raster Processing Polygon scanner systems are optimized for highest scan speeds and accuracy. The scan system employs a rotating polygon mirror for fast line scanning. With the aid of an external feed axis or web moving perpendicular to the polygon wheel‘s scan direction, a long area can be processed across the scan field‘s entire width in onthe-fly mode. The scanner is typically used for full-surface processing in a regular raster. Individual exposure patterns can be produced via a function that allows outputting a user defined bitmap for pixel-accurate control of the processing laser. Through the integration of high precision galvanometers and advanced control features such as SuperSync and TrueRaster additional flexibility in scanning strategies and highest accuracy becomes available

Optics The Line Scan Engine (LSE) provides integrated telecentric mirror optics for a compact all-in-one scan head, to address large areas at the highest performance. The hybrid system design permits using a variety of traditional glass f-theta objectives. The useable scan field is strip shaped and aligned to the polygon wheel's direction of scanning. Polygon Correction When required, two galvanometer scan axes can be used to permit compensation of polygon mirror inaccuracies as well as image field correction and enlargement of the working area so that scan lines may be positioned in a strip...
