Measuring the surface shape or displacement

Set the longest peak bar (the first peak), which shows that the measurement

target is in the focus, so that it extends to the right side of the vertical cursor.

Measuring the thickness or backside of a transparent object

When there is more than one light intensity peak, set the light intensity level bar so

that at least two surface peaks extends to the right.

Accuracy of the measurement differs depending on whether or not the light

intensity level is set properly. For more accurate measurement, set the light

intensity as high as possible within the range so as not to exceed adequate light

for measurement. Be sure not to set it too high or the measured value will be

retained and measurement will be disabled.

The displacement mode is used in this example. Stabilized measurement can be

obtained in the profile mode by making the same settings.

Refer to "Setting the Light Intensity Level" (page 3-8) for setting of the

displacement mode.

Refer to "Setting the Light Intensity Level" (page 4-8) for setting of the profile

mode.
