The EZ-0745 air-bearing ZC-axis is intended for integration into an XY-stage (e.g. EZ-0715). Due to the highly integrated design, only a low overall height of approx. 138 mm is required. The rotation angle is limited to ± 3°. A high repeatability of ± 1.5 μrad enables very precise alignment of the substrate. The Z-axis is secured against rotation via 2 air bearing pads and is dynamically driven by 2 opposing voice coils. An air-bearing pneumatic cylinder is integrated for weight decoupling. An individual, customer-specific adjustment of the Z-stroke is possible.
