A-361, dimensions in mm. Note that a comma is used in the drawings instead of a decimal point.

6-axis combination of A-361 (top) and A-523 (bottom): design for fiber positioning. (The coffee cup serves for size comparison.)

A-361 is an air-bearing XY-ThetaZ stage with direct drives. Designed as a parallel-kinematic multi-axis system, the platform moves in the X and Y directions as well as rotational in the Z axis. This stage offers ultra-high precision with a very low profile. The combination of the noncontact components results in frictionless movements. Thereby the A-361 offers not only ultra-high precision, but very high performance, and long service life. As the A-361 can be locked as needed, it offers excellent positional stability.

The A-361 can be mounted on a A-523 Z tip/tilt stage. This results in a compact 6 degrees of freedom motion system.

Air filter preparation kits
Compatible A-8xx cables
Multi-axis A-8xx controller
Integrated vacuum chuck

The stage is ideally suited for many high-precision applications, such as wafer inspection, fiber positioning, optics positioning, flat screen inspection, maskless lithography, and ultra-LED manufacturing. The noncontact design is ideal for cleanroom applications.

⁽¹⁾ The X and Y travel ranges and the rotation range in θZ are related. The values in the table show the maximum travel range for each axis, when all other axes are at the reference position.

⁽²⁾ Is directly related to the system stability (servo jitter); this depends on the servo drive used. The position stability can be improved by using ServoBoost^TM PLUS on an ACS SPiiPlus controller.

⁽³⁾ The calibrated accuracy can only be achieved with a controller-driven error compensation. The stage must be ordered with a controller from PI to reach these values. Accuracy values assume short duration and do not consider the long-term effects of thermal drift on the stage.

⁽⁴⁾ Assumes an air bearing operating pressure of 480 kPA (70 psi). The stage is designed for horizontal operation only.

⁽⁵⁾ To protect the stage against damage, it is recommended to connect an air pressure sensor to the E-Stop input of the controller.
