Z-Lift motion platforms were created to replace the inaccuracies of the ever present Z-Wedge vertical stages as well as reduce the footprint and improve performance of linear stages mounted in the vertical orientation. Every component in a motion stage adds to the total error. Since Z-wedges have a minimum of three machined components with complex angles, three sets of bearings, a motor via a coupling and an encoder, the result is a very inaccurate stage.

PATENTED NANO Z®

Increased demands for True NANO® metrology and process lead ALIO to design and manufacture the NANO Z® patent pending Z lift air bearing stage to exceed all past design issues of tip and tilt while increasing the accuracy to less than 100 nanometers with standard Renishaw Invar encoders.[/vc_column_text][vc_column_text]MECHANICAL BEARING Z STAGE

The advantage of this family of vertical Z-lift stages:

• Linear or voice coil motors
• High rigidity crossed roller bearings
• High force motors
• Linear encoders
• Air counter balanced
• Motor, bearings, encoder and counterbalance all on approximate centerline of the stage
• Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
• Excellent dynamic performance

COMPACT VOICE COIL Z STAGE

The advantage of this family of vertical Z-lift stages:

• Compact design, low profile height
• Voice coil motors
• High rigidity crossed roller bearings
• Linear encoders
• Air counter balanced
• Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
• Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
• 4X to 10X more precise than Z-wedge stages.

GEOSYMMETRIC™ Z STAGE, LINEAR MOTOR DRIVE WITH MAGNETIC COUNTERBALANCE

The advantage of this family of vertical Z-lift stages:

• Sturdy design minimizing Abbé errors
• DC Servo Linear Motors
• High rigidity crossed roller bearings
• Linear encoders
• Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
• Payload can mount directly to the face or top surface of the stage to eliminate the weakness and resonant frequency issues associated with additional brackets
• 4X to 10X more precise than Z-wedge stages

LINEAR MOTOR COUNTER BALANCED Z STAGE

The advantage of this family of vertical linear stages:

• ALIO’s nano-precision design
• Linear servo motors
• High rigidity crossed roller bearings
• Linear encoders
• Counter balanced with dual frictionless cylinders balancing the load. The cylinders are in-line with the motor, bearings and encoder thus they do not create an Abbé error
• Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.

AIR BEARING LINEAR MOTOR Z STAGES

The advantage of this family of vertical linear stages:

• Granite base to ensure exceptional flatness and straightness.
• Linear servo motors
• High rigidity, nano-precision air bearings
• Linear encoders
• Counter balanced with dual frictionless cylinders balancing the load. The cylinders are in-line with the motor, bearings and encoder thus they do not create an Abbé error
• Counterbalance brackets can be changed if required to assure counterbalance force is transferred through the mass center of the load.
• Motor, bearings, encoder and counterbalance all on approximate centerline of the stage
