Aerotech AVS100 Series Mechanical-Bearing Screw-Driven Lift Stage

Aerotech’s AVS100 series stages offer a solution for applications that require

very small incremental movements in elevation above a horizontal plane.

Low profiles and precise motion capability make these stages ideal for use

in semiconductor wafer inspection and testing, fiberoptics assembly and

inspection, automated tool alignment, machine vision inspection systems

and laser machining applications.

Design Features

• Long-life linear guide bearing system

• Submicron closed-loop positioning

• Low-cost, high-performance stage

• 6. 13 and 25 mm travel models

• Precision-ground ball screw

• Quality Design Provides Superior Performance

The AVS100 series provides precise elevation of a load in a vertical plane. 

Rotational movement of a precision-ground ballscrew is converted into

vertical elevation of the AVS100 series tabletop.

Sealed linear motion guide bearings with integral wipers are incorporated

to provide excellent payload capability, long life, and smooth, precision

motion. Stable and parallel vertical motion with no rocking or horizontal

deviation of the platform is ensured.

Careful mechanical design allows the AVS100 series to achieve submicron

resolution and still maintain a compact profile. The optional factory

calibration option is available to further increase standard accuracy and

repeatability.

A Better Approach to Vertical Motion

The vertical lift approach offers an alternative to traditional Z-plane oriented

stages. Not only do the AVS100 series stages offer a lower profile, but the

load can also be accessed easily from any side. And by centering the payload

over the bearings, there are no cantilevering effects. The AVS100 series stages

provide a space-saving alternative to traditional XYZ systems and are equally

suited to laboratory and industrial applications. Optional stage finishes are

available for various environments, including vacuum preparation.

All AVS100 series stages are equipped standard with integral limit switches and

mechanical hard stops. The stage tabletop is treated with a Teflon®-impregnated

hardcoat (Rockwell 62 hardness) that is scratch-resistant and provides outstanding

protection in the harshest environments. The stage itself has a black anodize finish.
