ARC-series Optical Scanners for high volume consumer applications 3D Printers Laser Marking Laser displays (light show) LIDAR systems Relatively large, slotted output shaft Integrated back-supporting mirror mount Strong position feedback with low noise Compact and lightweight Wide scan angle of 40 to 60 degrees Industry-standard galvo performance at the lowest possible cost GENERAL DESCRIPTION The ScannerMAX ARC-series represents an entirely new way of constructing an optical scanner. ARC is an acronym, which stands for “Actuator with Rectangular Coil”. In this new design, a small number of precision parts are assembled together along with a highly-optimized rectangular coil, to deliver industry-standard performance at a cost that is a small fraction of galvanometers commonly found in the marketplace. Due to the fact that this series of optical scanners delivers performance similar to conventional galvanometers, ARC-series scanners can be used in any application where galvos are commonly found, including laser displays and laser marking. However, the very low price-point of this new galvo design enables consumer-grade applications, including point-of-purchase displays, 3D printers and LIDAR systems. Although the design is completely flexible and adaptable, the ARC series has been manufactured in three separate sizes: the ARC 506, intended for 1-5 mm apertures; the ARC 5510, intended for 10-12 mm apertures; and the ARC 12532, intended for 20-50 mm apertures. The ARC series design is licensable to certain OEMs, thus helping to further enable high volume applications. Document Number: ARC-506-9020 Revision: 26-April-2024
