Polygon Scanner Systems TrueRaster technology for additional flexibility/accuracy* USP-Laser (optional other laser) Laser control Axis master position Mechanical axis *available in specific models High-speed Scanner for Line-by-line Processing High Throughput Raster 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 scanner systems from Next Scan Technology are optimized for highest scan speed stability 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. 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 patterning touchscreen surfaces or scribing solar cells, to micro-drilling and processing of electronic components, glass and plastics, as well as sensor manufacturing. 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 actuators and advanced control features such as SuperSync and TrueRaster additional flexibility in scanning strategies and highest accuracy becomes available. Next Scan Technology offers a wide range of polygon scanner systems allowing customization for optimum efficiency. Associated with

Polygon Scanner Systems Full Telecentric Optics Synchronization Functionality The Line Scan Engine (LSE) provides integrated full telecentric mirrors for a compact all-in-one scan head, to address large areas at the highest performance. The mirror based concept allows for application specific customization when using high power legacy lasers and stitching of scan heads, enabled through a staggered or in-line configuration and complementary controls. Ultra short pulsed lasers normally used with this system are typically equipped with an internal clock source that regulates the time points of...
