Aerotech AVF75-400 Voice Coil Driven Objective Focuser

The AVF75 Voice Coil Driven Objective Focuser enables microscope objective

and optics positioning at a large travel without sacrificing speed or nanometer

-level performance. Designed to accommodate optical instruments and

next-generation laser micromachining applications, the AVF75 is ideal for

demanding optical positioning applications that require high precision, high

throughput and long travels.

MPS-LZS stages define a new benchmark for high-quality vertical motion

that breaks the traditional tradeoff between precision and price.

For demanding applications that require a careful balance of performance

and cost, you no longer have to compromise on core technology.

MPS130LZS stages feature anti-creep, crossed-roller bearings; ironless

linear motors with exceptionally high force density; and an adjustable

pneumatic counterbalance to offset up to 12 kg payload – so you get

smooth, precise motion. Plus, MPS-LZS stages are form-factor compatible

with our industry-leading ANT-LZS vertical nanopositioning stages, giving

OEMs an easy and efficient means to scale.

Integrated Counterbalance

MPS-LZS stages are equipped with a minimally influencing pneumatic

counterbalance to offset the gravitational forces from the carriage and

payload. It includes a precision regulator for the exact dialing-in of the

counterbalancing force. Unlike spring or magnetic counterbalance

designs, the pneumatic counterbalance can be easily adjusted to exactly

offset your payload’s weight—no ballast or counterweights needed.

The counterbalance is installed standard on the left side of the stage;

however, you can easily reconfigure it for right-side operation.

Noncontact Direct-Drive Technology

Only noncontact direct-drive technology offers the robust, accurate and

high-speed positioning necessary for mass production of precision devices.

Compared to traditional screw-driven vertical and lift stages, MPS-LZS

stages can move and accelerate faster and more precisely. This is because

MPS-LZS stages use an ironless linear motor that eliminates cogging effects

that would otherwise cause position errors and disturbances. Coupled with

anti-creep, crossed-roller bearings, MPS-LZS delivers smooth, consistent

vertical motion with outstanding dynamic characteristics to enhance your

process capability at an attractive price point. The optimized drive and

bearing combination, packaged in a compact form factor, offers distinct

performance advantages in many applications such as high-precision

positioning, fiber alignment, optics manufacturing and inspection, sensor

testing and scanning processes that demand smooth and precise motion.

Flexible System Design

MPS-LZS stages feature convenient mounting patterns in the base and

tabletop to allow for easy system integration. Multiple stages can be

assembled together for flexible system designs and application-specific,

multi-axis configuration. Because MPS-LZS stages are form-factor, drop-in

compatible with our industry-leading family of ANT nanopositioners, you

can effortlessly combine MPS-LM and ANT stages into multi-axis systems

to achieve a balance of extreme performance and cost effectiveness.
