Autofocus final check

An option to perform a final autofocus check is available from the

Auto Focus tab in the Probe Library.

Enabling a final check helps to avoid missing an optimum focus point

when autofocusing with a search distance smaller than 1 mm and a

magnification greater than 20 x. An optimum focus point can be

missed due to skipping of the focus frames during the focus search,

machine drive mechanics, changes in lighting, or the objective lens

being used.

A final check compares the difference in contrast values of frames in

the range of 5 µm above to 5 µm below the initial focus point. If there

is a point with a larger contrast value found the system will focus on

the point of greater contrast.

To enable the the autofocus final check:

 Select Probe>Probe Library...

 Select the target camera and target magnification

 Select the Autofocus tab

 Check the check box next to Enable final check

Click Probe>Probe Library... Check the check box next to Enable final check
