Description
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.
Data sheet.
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.
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
LINEAR MOTOR MAGNETIC COUNTER BALANCED Z STAGE FOR HIGH FREQUENCY AND QUICK FOCUS
The advantage of this family of vertical linear stages:
- ALIO’s nano-precision design
- Linear servo motors
- High rigidity crossed roller bearings
- Linear encoders
- Removes the need for air lines to counter balance and can be designed for motion AWAY from crashing on a power-off situation
- Motor, bearings, encoder and counterbalance all on approximate centerline of the stage.
