17.5 X-Y Calibration using Capture Calibration and

Autocalibration

17.5.1 Capture Calibration

Scanners are calibrated by setting parameters in the NanoScope software using the Capture

Calibration command. The basic calibration procedure using version 5.XX software and a 10-

micron calibration reference (see Figure 17.1e) is described below.

1. With the Scan rate set to 2.44 Hz and Number of samples parameter to 256, a full Capture

Calibration requires approximately 70 minutes.

Note: Increasing the Number of samples or decreasing the Scan rate signiﬁcantly

increases the required time.

2. Using the mouse, click on Realtime > Capture > Calibration. The Capture Calibration

dialog box lists twelve parameters used in the calibration procedure (see Figure 17.5a).

3. If this is a first-time calibration, or if the microscope’s calibration has not been checked

within the last three months, verify that all parameters are selected.

4. Click on

CAPTURE to initiate the automatic calibration routine.

Note: The microscope begins an automatic series of scans on the reference which

require approximately one hour to complete. During each scan, the scanner

moves the piezo using carefully calculated movements. Many of these

movements are unusual, giving rise to a variety of images which do not

resemble the normal reference. For example, pits may resemble trenches and

features may be presented at various angles.

5. As each routine is executed, adjust the scan slightly to optimize the calibration image using

the Capture Control dialog box displayed on the control monitor throughout the calibration

routines (see Figure 17.5b).
