To remove the Z scanner:

  1. Using your right hand, unplug the Z scanner connector cable from the side of the Dimension FastScan scanner head.
  2. Using your left hand, grasp the Z scanner; try not to touch the bottom surface of the Z scanner, where the probe is mounted.
  3. Turn the vacuum for the Z scanner/probe holder off:
  4. Pull the Z scanner down and free of the XY scan head.

To remove the Dimension FastScan scanner:

  1. Unplug the connectors on both sides of the Dimension FastScan scanner, including the vacuum hose.
  2. Using a 3/16" hex driver, unscrew the clamp holding the Dimension FastScan scanner in the dovetail mount.
  3. Using the handles at the top and left hand side of the Dimension FastScan scanner, carefully lift it upwards and out of the dovetail.
  4. Place the Dimension FastScan scanner in the box it shipped in or on a level surface free of clutter.
CAUTION: The Z scanner apparatus is expensive and fragile. NEVER place the Dimension FastScan scanner down in such a way that the Z scanner comes into contact with the table. Lower the Dimension FastScan scanner onto the table with the labeled front piece facing upward.
  1. Click Next. The wizard will display a window with instructions for installing the Dimension Icon optics assembly and a diagram to help you identify the relevant components:

To connect the optics assembly:

  1. Gently slide the Dimension Icon optics onto the left-side dovetail; push them all the way to the right until they come to a hard stop.
  2. Tightening the clamping screw with the 3/16" hex driver.
CAUTION: Be very careful to adjust only the optics clamping screw. It is the middle of 3 screws located on the optics assembly. Turning the other screws could move the system optics out of alignment.
  1. Plug in the optics cables.
  1. Click Next. The wizard will display a window with instructions for installing the Dimension Icon scanner and a diagram to help you identify the relevant components:

To connect the Dimension Icon scanner:

  1. Carefully remove the Dimension Icon scanner from its container and slide it down into the dovetail groove of the Z-stage.
  2. When sliding the Dimension Icon scanner into the dovetail, make sure that the probe tip will not touch the sample. If it appears that the tip may touch when the scanner is fully inserted in the dovetail, raise the Z-stage by selecting Microscope > Withdraw several times, or by selecting Navigate > Focus Surface and raising the Z-stage upward.
  3. Tighten (by turning counterclockwise) the screw located on the right side of the Dimension Icon scanner dovetail to lock the scanner in place.
  4. Insert the black 47-pin connector plug (from the scanner) into the socket to the right of the scanner.
NOTE: Dovetail engagement actuates with a spring. Failing to engage the spring-loaded dovetail causes a large increase in image noise due to reduced rigidity of the mechanical support of the scanner.
  1. Click Finish. Wait for the NanoScope popup to appear, informing you that a new head has been detected and NanoScope must close:

 
  1. Click OK; NanoScope will close.
  2. Manually restart NanoScope 8.15 to proceed with your experiments using the new scanner.
NOTE: You will need to initialize the stage when NanoScope restarts. Click OK in the dialogue that appears.
