Translation stages

An integrated ¥and theta stage uses air bearings to provide a noncontact system that includes patented servo feedback technology. The Z-Theta stage design eliminates mechanical guiding members, thus reducing possible pinch points. The stage comes in sizes with strokes ranging from 25 to 50 mm. The high-performance stage incorporates closed-loo¥encoder technology with resolution to 0.16 µm and z-axis positioning to ۬.5-µm accuracy and 䔮-µm repeatability at velocitie
