2.3. Securing the Stage to the Mounting Surface
W A R N I N G : Do not attempt to manually move the ADRS if it is connected to a power
source.
W A R N I N G : Make sure that all moving parts are secure before moving the ADRS.
Unsecured moving parts may shift and cause bodily injury.
W A R N I N G : The ADRS must be mounted securely. Improper mounting can result in injury
and damage to the equipment.
The mounting surface must be flat and have adequate stiffness in order to achieve the maximum
performance from the ADRS stage. When it is mounted to a non-flat surface, the stage can be distorted as
the mounting screws are tightened. This distortion will decrease overall accuracy. Adjustments to the
mounting surface must be done before the stage is secured.
Inspect the mounting surface for dirt or unwanted residue and clean if necessary. Use precision flatstones
on the mounting surface to remove any burrs or high spots. Clean the mounting surface with a lint free cloth
and acetone or isopropyl alcohol and allow the cleaning solvent to completely dry. Gently place the stage on
the mounting surface.
N O T E : To maintain accuracy, the mounting surface must be flat to within 1 µm per 50 mm.
N O T E : The ADRS is precision machined and verified for flatness prior to product assembly at the
factory. If machining is required to achieve the desired flatness, it should be performed on the mounting
surface rather than the ADRS. Shimming should be avoided if possible. If shimming is required, it should
be minimized to retain maximum rigidity of the system.
ADRS series stages have a fixed mounting pattern (as shown in Figure 2-4 ).
Tightening torque values for the mounting hardware are dependent on the properties of the surface to which
the stage is being mounted. Values provided in
Table 2-1 are typical values and may not be accurate for your
mounting surface. Refer to Section 2.2. for specific model mounting locations and dimensions.
