SATURN-15 GALVO
Description
The Saturn 15B optical scanner is specifically designed to meet the demands of applications having apertures in the 10mm to 15mm range, such as laser marking, laser welding, via-hole drilling, SLS 3D printing and large-beam laser displays. Several coil configurations are available including one with very low inductance and low coil resistance optimized for the fastest step-times, and another with moderate resistance and inductance optimized for large-signal applications such as laser displays.
Features of the Saturn 15b Galvanometer
- The Saturn 15B has nearly the same dimensions as a Cambridge model 6230 but around half the weight, so it may serve as a drop-in replacement that also offers a significant performance upgrade, particularly in applications that are sensitive to electrical power consumption and heat generation.
- The Saturn 15B has a rotor inertia of 0.54 Gm•Cm2, which is an inertia presently not served by other galvos on the market today. This rotor inertia allows more of the motor’s torque to be transmitted to the mirror and less to be expended moving the rotor itself. This rotor inertia, coupled with our highly efficient and patented X3 magnetic design, allows this scanner to do the same job as conventional galvos, while generating around 1/3 of the heat.
- Our patented position sensor design allows for wide-angle scanning up to 110 degrees optical with high output and low noise.
