Abstract
A high precision z-theta stage having a horizontal translation axis (z-axis) and a rotary axis (theta-axis) parallel with the translation axis comprises parallel spaced apart linear translation stages, a carriage supported between the parallel translation stages, and a rotation stage carried by the carriage between the parallel translation stages. Each brushless linear motor is connected to the carriage to apply translation forces in a horizontal plane intersecting the vertical center of gravity.
