Planar Air Bearing System
Patent Pending 2 Axis planar air bearing system has set the mark in the world of 6-D Nano Positioning™. With 300 mm to over 3 meters of X and Y travel this product family has no equal for True Nano ™ precision. NIST traceable laser data has measured this product over meters with nanometer precision in all 6 degrees of freedom of a moving member. Expect standard flatness of < 1 µm/meter with less than < 1 arc second of pitch, yaw and roll. Standard repeatability < 60 nm with optional 10 nm capable in the product family.
Linear Air Bearings
Single axis linear air bearings are available in horizontal or vertical orientation as shown. The linear product family of air bearings utilizes ironless linear servo motors with variable forces depending on customer needs. These product family standard designs are from 25 mm to 3 meters of travel each with nano precision.
Patented NANO Z®
Increased demands for True NANO® metrology and process led 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. The counterbalanced NANO Z® can easily hold heavy vacuum wafer chucks and still excel with nano-precision over 24 mm of travel.
