Aerotech's AVS100 series stages offer the ideal solution for applications that
require very small incremental movements in elevation above a horizontal plane.
Their small 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.
Quality Design Provides Superior Performance
The AVS100 Series' precise elevation of a load in a vertical plane is accomplished
with a moving wedge design. The precision-machined wedge block converts horizontal
movement from a precision-ground ball screw to vertical elevation of the AVS100
Series stage's tabletop. Linear motion guide bearings are incorporated to provide
excellent payload capability, long life, and smooth, precision motions. Stable
and parallel vertical motion with no rocking or horizontal deviation of the
platform is ensured. Careful design of the wedge angle and bearing system allow
the AVS100 Series stages to achieve submicron resolution and still maintain
a compact profile. The HALAR 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 with which to contend.
Equally suited to laboratory and industrial applications, the AVS100 Series
stages provide a space-saving alternative to traditional X-Y-Z systems. Optional
stage finishes are available for various environments, including vacuum preparation.
Additional Standard Features
All AVS100 Series stages are equipped standard with integral limit switches
and mechanical hard stops. The stage tabletop is treated with a TeflonTM-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.
Motor and Drives
The AVS100 Series includes Aerotech's high performance NEMA 23 frame-size BMS
series brushless, slotless servomotor. The slotless motor has zero cogging and
therefore is optimized for applications requiring very smooth motion. Aerotech
manufactures a wide range of matching drives and controls to provide a fully
integrated and optimized motion solution.
