Saturn 1 Galvo

Description The Saturn 1 is a galvanometer-based optical scanning system, designed to achieve the highest RMS performance of any scanner in the 1mm to 4mm aperture range. It is designed for applications such as optical coherence tomography (OCT), confocal microscopy, small beam-laser marking, laser entertainment displays, optical layout templates and raster image projections. Features of the Saturn 1 Galvanometer The Saturn 1 optical scanner has a low coil resistance that allows it to achieve the highest acceleration and RMS duty cycles without production of excess heat inside the galvo. Due to the low inertia rotor assembly and special bearing materials, the Saturn 1 boasts the highest peak torque-constant-to-inertia ratio of any moving magnet galvanometer available. With our patented X3 magnetic circuit the Saturn 1 reaches scanning speeds of 5kHz small signal bandwidth with far less drive power and heat generation than before. Systems achieving 7.5kHz small signal bandwidth are routinely delivered to clients. Our patented position sensor design allows for wide-angle scanning up to 110 degrees optical with high output and low noise. The Saturn 1 incorporates all the design features of the ScannerMAX Saturn series, including a half-inch round body diameter, back supporting mirror mount design, high-output and low-noise position detector. In combination with our MachDSP digital servo driver we are able to achieve performance greater than other similar galvanometers. We also offer coil configurations optimized for certain imaging applications and reduced heat scenarios.
