Nano Z® – Dual Voice Coil Stage with Air Bearings

Increased demands for True NANO® metrology and processes led ALIO to design and manufacture the NANO Z® patented Z lift air bearing stage to overcome legacy design issues associated with tip and tilt while attaining accuracy of less than 100 nanometers using standard Renishaw Invar encoders. The counterbalanced NANO Z® can easily hold heavy vacuum wafer chucks and still excel with nanometer-level precision over 24 mm of travel. It is therefore perfect for high demanding applications in the semiconductor and metrology industry.

GeoSymmetric Voice Coil Z Stages

ALIO’s family of GeoSymmetric Vertical Stages provides the foundation of novel designs for ultra and Nano Precision performance. Structurally designed to exceed application performance demands. Built for precision with application dependent counterbalances. Those stages use linear or voice coil motors, highly rigid crossed roller bearings, high force motors, and linear encoders.

The counterbalance, motor, bearings, and encoder are all placed on an approximate centerline of the stage. The 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, associated with additional brackets, all of which makes ALIO’s voice coil stages 4x to 10x more precise than Z-wedge stages. This makes it great for any application within Life and Health Science, Microscopy or Nano Metrology.

Long travel Z Stages with Linear Drives

ALIO’s family linear motor driven, vertical Z-lift stages are characterized by a cow profile height and extreme long travel ranges. Using high precision crossed roller bearings, and linear encoders, the stages can be equipped with Magnetic Spring Counterbalances or a frictionless Air Bearing Pneumatic Cylinder. The stages are have, the counterbalance, motor, bearings, and encoder all placed on an approximate centerline of the stage. The payload can mount directly to the face of the stage and drive up to 200mm in vertical direction.

High Load and Force Z Stages with Pneumatic Brake

ALIO offers vertical Z stages with precision ball screw driven by a frameless torque motor.

With its standard pneumatic release, spring engage brake it can lift up to 20kg without an additional counterbalance. For even higher loads, this series offers a Pneumatic Boost option using a frictionless pneumatic counterbalance to boost the payload capability to 50kg. Even with such high loads, those stages can achieve down to +/- 100 nm bi-directional repeatability over ranges of up to 50mm. An ideal stage for applications requiring high loads and long travel ranges without compromising precision.

Stages can be used in broad field of application from Semiconductor Lithography or Metrology, Large measurement tools or even in harsh industrial environments.

Precision Crossed Roller Bearing Linear Stages

ALIO’ Nano Precision XY Monolithic product is a 3-plate system with unmatched 6-D performance.  With years of testing, continuous design improvement, and unique manufacturing protocols, the ALIO precision crossed roller bearing stages have no equal for quality and performance. Our linear stage product family begin with 25 mm travel and go up to 400 mm of travel with motor and encoder options to fit your application needs.

Monolithic XY Linear System

ALIO’s XY monolithic True Nano® motion systems performance is unequaled for 6-D Nano Precision®. With nanometer straightness and flatness you can be assured that your point precision is True Nano®. This stage family comes with enclosed or open center versions from 50mm travel to 450mm travel. Standard axis bi-directional repeatability is less than 50 nanometers with optional 10 nanometers bi-directional repeatability for demanding metrology or manufacturing needs. Stages can come with NIST traceable data assuring nano precision not just marketing data sheet optimism.

Linear CM Servo Motor

ALIO produces CM linear servo stages for customers that need less costly True Nano® precision. CM servo motor stages still have the ALIO 6-D precision with less linear force for smaller and lower acceleration applications. The stage family uses the precision anti-skid bearings common to all other ALIO mechanical bearing products with the same 25 mm to 400 mm travel ranges.

Standard Hybrid Hexapod

ALIO’s Hybrid Hexapod® ALIO’s new, patented approach to six DoF hexapod positioning, resulting in nano-level accuracy at any working point. This makes this a unique design ideal for automated application in Photonics, Microassembly, Laser Processing or Metrology – literally any application requiring 6- degrees of freedom positioning with nanometer/arc-sec levels of incremental motion and repeatability is a good fit for this product where product sensor resolution improvements are driving the need for higher precision. It is proven, that this point-precision design is two orders of magnitude more precise than any competitive hexapod built today.As other competitive hexapods use six links to accomplish even a single DoF movement. Position errors add in this arrangement.

The modular design makes it scalable from coffee cup size to meters in height with dozens of kilograms payload, working in atmosphere or high vacuum, all with 6-D precision.

MINI Hybrid Hexapod

ALIO’s MINI Hybrid Hexapod® is ideal for automated lens alignment/bonding to CCD arrays. It has been helpful in building camera array modules, translational OIS, telescopic integrated lenses for miniature cameras used in every day products like cell phone cameras and drones. Any application requiring 6- degrees of freedom positioning with nanometer/arc-sec levels of incremental motion and repeatability is a good fit for this product where product sensor resolution improvements are driving the need for higher precision.

AngularesTM – Extra large Tip/Tilt Range Hexapod

The 60-degree tip/tilt travel of the AngularesTM Hybrid Hexapod® is by far the most angular travel range available from any 6-Degree-Of-Freedom (6-DOF) positioner on the market. It is perfectly suited for applications including aspheric and freeform optical metrology, silicon photonics packaging and probing, laser micro processing (non-planar substrates and taper control), wafer metrology, camera module alignment and assembly, sensor/image stabilization testing, and optical element and fiber alignment.

The AngularesTM  is capable of unlimited XY travel, Z travel for 62 mm which can be increased to 208 mm using other tripod models, tip/tilt travel of 60 degrees (+/- 30 degrees) with continuous 360 degree Theta-Z, XYZ bidirectional repeatability of less than +/- 0.6 arc-seconds, velocity up to 100 mm/second XY and Z, and less than 10 nanometers linear and 0.1 arc-seconds angular minimum incremental motion.

Special Task Hybrid Hexapods

ALIO’s modular and versatile Hybrid Hexapod® concept allows various adaptions and customization towards our customer needs. Such can range from applications with several dozens of kg load and high force requirements to totally novel design with large apertures.

High Angle Tripods

ALIO’s modular designs allow the use of high precision Tripods for applications requiring high angular movements without the need of purchasing a full six axes system. Depending on the specific type and configurations, rotational movements around the x and y axis of up to +/- 30 degree, and 360 degree around the z axis are possible. Of course, all with Nano Precision.
