GeoSymmetric Voice Coil Z Stages ALIO's GeoSymmetric™ Vertical Positioning Stages use voice coil or linear direct drives, high precision crossed roller bearings, and various counterbalance options within a unique and innovative design concept. Unique geometric shapes provide mounting surfaces on multiple faces of the stage for flexible installation options. Being able to mount the payload directly to the face or top surface of the stage helps to eliminate weakness and resonant frequency issues associated with additional brackets. The "Symmetric" part of the family's name originates from the arrangement of the components used. The counterbalance, motor, bearings, and encoder are all placed on an approximate centerline of the stage, i.e. they are integrated in a way that their masses are symmetrically distributed over the stage. This series of stages has been built for precision with application dependent counterbalances, and has been structurally designed to exceed application performance demands (with bidirectional repeatability down to +/-45nm, travels from 6 to 70mm, and load capacities of up to 30kg). Being 4x to 10x more precise than Z-wedge stages makes ALIO's GeoSymmetric™ Vertical Positioning Stages great for any application within the semiconductor industry, microscopes for life and health science, or numerous metrology applications.

Nano Z® – Dual Voice Coil Stage with Air Bearings When Nanometer-Level Vertical Precision Is the Priority Some applications place ultimate Z-axis precision above almost every other consideration. ALIO's patented NANO Z® architecture combines air bearings with dual voice-coil motors to provide frictionless vertical motion in a compact platform. By aligning vertical force with the payload, the architecture reduces the cantilever effects that can translate into pitch, yaw and roll errors at the work point. The system offers up to 50 mm of travel, while variable counterbalancing enables demanding payloads such as wafer chucks to be managed without surrendering nano-level positioning performance. Air-bearing operation also eliminates mechanical contact and associated friction, supporting extremely smooth motion and repeatability into the low double-digit nanometer range. For semiconductor processing, advanced metrology and other applications where vertical motion can directly influence measurement or process integrity, NANO Z® provides precision by architecture rather than compensation.
