Abstract
A high accuracy, orthogonal motion stage for microscopes and the like uses three frames for orthogonal motion. The lower most frame has provided thereon a series of downwardly depending ramps. An actuator plate having correspondingly positioned, upwardly directed ramps is translated with respect to the lower most frame to raise and lower the frames.
