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.

Water cooled high precision z-theta stage

A Cartesian gantry system having an expansion joint between an X-bridge stage and a Y-translation stage comprises a flexure plate having surfaces secured to the X-bridge stage and the Y-translation stage and bolster flanges extending between the X-bridge stage and Y-translation stage to resist twisting or rotation of the X-bridge.

High precision z-theta stage

A dual-function, three-axis positioning system having a high precision z-theta state with a horizontal translation axis (z-axis) and a rotary axis (theta-axis) parallel with the translation axis and a second horizontal translation axis (x-axis) comprises parallel spaced apart linear translation states, a first carriage supported between the parallel translation stages, and a rotation stage carried by the carriage between the parallel translation stages. A removable or permanently fixed second carriage is mounted on or being part of the first carriage.

Dual-function three-axis positioning system

A high precision laser machining apparatus 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. Mounted on the same base plate is a laser optics support stage and a workpiece advance mechanism.
