Mounting Surface Quality and Preparation
The surface to which the stage will be mounted should be flat and have adequate stiffness in order to achieve the
maximum performance from the A-62x. When the A-62x series stage is mounted to a non-flat surface, the stage
can be distorted as the mounting screws are tightened. This distortion will decrease the overall accuracy of the
stage. The effects of flatness on mounting are illustrated below.
To maintain accuracy, the mounting surface should be flat within 1 µm per 150 mm. A laboratory grade AA
granite surface plate is recommended. Do not shim under the stage base.
Prepare the mounting surface and bottom of the stage base with precision flat stones to remove any burrs or high
spots. Clean the mounting surface and bottom of the stage with the appropriate cleaners (isopropyl alcohol).
6.2.
Mounting Orientation
The A-62x is suitable for various mounting orientations, such as horizontal, vertical, and inverted. PI
recommends that you review your payload and orientation conditions with a PI engineer before purchasing this
product.
