Check out our Saturn series of scanners


Staff member
Hi Everyone and welcome to the ScannerMAX forum!

I'd like to invite you to check out our Saturn series of galvanometer-based optical scanners.

Currently there is only one scanner in the Saturn series, but there are more planned in the future. Our current offering is model Saturn 5, intended primarily for use in the 5mm range, although this scanner is also suitable for apertures ranging from 3mm all the way up to 8mm.

The Saturn series of scanners is completely unlike the galvos made by all other manufacturers. Almost all other galvos use a similar construction, based on a design originally invented in 1976, and intended to be a bearing-free resonant scanner. Then in 1992, once Neodymium Iron Boron magnets reached broad availability, this design was adapted to galvanometric scanning. But since that time the design hasn't changed much, and almost all manufacturers adopted this rather conventional approach to creating a moving magnet motor.

The ScannerMAX approach is unlike the conventional design in many ways. The way we form a magnetic circuit results in a magnetic field strength that is significantly stronger than all others. The way we form a rotor and attach the mirror is also stronger. The position sensor offers a stronger signal-to-noise ratio and lower capacitance, and the bearings are made with the strongest nitrogen alloy steel available. Due to the way in which the coils are formed and then placed into the magnetic circuit, the motor runs cooler. Putting all of this together there is a simple formula: Stronger + Cooler = Faster!

Please let us know your challenges and we'll be happy to answer any questions.

PS: Galvanometer scanners are also called "galvos", although this is a term created decades ago and it only vaguely applies to modern mechanical scanners of today. Nevertheless the term Galvanometer and Galvo are useful to distinguish this kind of scanner (a motor with a mirror attached to its shaft) from other types of optical scanners, such as electro-optic, acousto-optic, resonant or polygonal scanners.
