OPTICS ILLUMINATION ADJUSTMENT
After lowering the optics tower to focus the camera, adjust the illumination level of the video image
displayed on the Dektak 150 monitor using the toolbar icons (see
Dektak Database Window on page
), or the Up and Down arrow keys on the keyboard.
You can change the increment by which the illumination changes at each click. See

The sample should be in focus whenever the system is nulled by lowering the stylus onto the sample
surface. If not, see
Adjusting the Optics on page 9-17
STYLUS RETICLE ALIGNMENT
NOTE –
If the stylus is on the surface and is not close to the center of the field of view, then
first try adjusting the optics (a much easier procedure) before attempting to adjust the reticule.
To adjust the camera position, see
Adjusting the Optics on page 9-17
.
The stylus reticle can be aligned to a newly installed stylus, or to allow for tolerances in the stylus
head. If the stylus tip is not properly aligned with the reticle in the camera view pane, adjust the
reticle position. The reticle provides a reference point when positioning the sample stage. Because
the stylus is raised off the surface during stage positioning, the reticle indicates where the stylus will
touch on the surface.
NOTE –
During initial set up, you may need to adjust the camera position to move the stylus
within the stylus crosshair box. To adjust the camera position, see
.
Complete the following steps to align the reticle with the stylus tip.
