Galvanometer Based Optical Scanner: 6200H Moving Magnet Closed Loop Galvanometer Specifications Cambridge Technology brings you the smallest galvanometer available on the market today. Designed for applications where size is of the greatest importance the 6200H compact footprint allows the 6200H to be easily incorporated into any system without compromising space. Our 6200H can be designed and optimized for speed, size, cost and accuracy with typical beam diameters of 3mm or smaller.
