1.3 HS1.
The HS1 is manufactured from a high performance Aluminium 7075 alloy. PZT actuators
are preloaded within the HS1 and supply the driving force for stage movement. The
flexure hinges, which form the guidance mechanism, are cut into the stage using electric
discharge machining (EDM). The PZT actuators are oriented parallel to the stage motion
direction. There are no serviceable parts in the HS1 stage.
A stage direction arrow is located on the side of the stage. This arrow indicates which
direction the stage moves when a positive voltage is applied. For XY or XYZ systems, an
identification label of either X (CHANNEL 1) or Y (CHANNEL 2) or Z (CHANNEL 3) is
located near the direction arrow. This identification, X, Y or Z, describes which driver axis
that particular stage should be connected to.
2 INSTALLATION
The HS1 may be installed either vertically or horizontally. When installed vertically the
stage direction arrow should be pointing upward. Larger loads may be carried when
mounted in the horizontal direction. It is always advisable to minimize the load carried by
the Nanopositioning stage. Heavier loads reduce the stage response time and may
cause fatigue and /or reduced motion.
2.1 Installing a single axis HS1 unit.
To install a single axis HS1 use the following steps.
•
On the surface that the HS1 is to be mounted on, tap M3 holes on a
52,50X52,50mm square.
•
Make sure the surface to be mounted to is clean, flat, and free of burs.
•
Using a lint free cloth, gently wipe off the bottom of the HS1 to remove any
particles or dust.
•
Use M3 Socket screws to secure the stage. Use a maximum torque of 0.5 Nm.
Attempt to minimize the torque between the moving and fixed part of the stage
during tightening.
IMPORTANT!
Check for ground loops (
Section 3
) between the HS1 and the mounting
surface.
Items can be attached to the scanning stage using one or more of the M2.5 holes that
are tapped on the moving part of the stage. These M2.5 holes are on a 29mm square. To
attach an item to the scanning stage, use the following procedure.
•
Using a lint free cloth, gently wipe off the top of the HS1 to remove any particles
or dust.
•
Make sure the item to be attached is flat and free of particles or dust.
•
Locate the item to be attached and ensure that it does not come into contact with
any portion of the stage other than the moving portion. Ensure that the item being
attached does not come into physical contact with any other item.
•
Tighten the M2.5 screws, using a maximum torque of 0.5 Nm. Attempt to minimize
the torque between the moving part and fixed part of the stage during tightening.
