8.1.1 “Focus” Section
It is possible to work either in autofocus (AF) or manual focus (MF).
Clicking on “
AF ” button will allow the camera to work in autofocus mode.
It will be sufficient to position the target to be observed in front of the camera lens and the focus will be obtained.
The autofocus will be independent of the optical or digital zoom value of the camera: the camera must have
enough contrast in the sample to be observed.
In the case of objects with low contrast, it is possible that the camera can not get the focus. In this case we re -
commend using manual focus.
• It is important to remind that the camera doesn’t have an infinity autofocus capability. The user must
approximately focus the specimen with the microscope focusing knobs. From this moment the cam-
era will be able to automatically focus the specimen when the stage is moved to another position or
the slide is changed on the stage.
Clicking on “ MF ” button, the camera will work in manual focus mode. Activation of the MF button automatically
activate the “ MF ” slider

, with which you can operate to focus the camera without having to act on the
microscope focusing knobs.
Clicking on “ Click F ” the camera is taught which is the optimal focus for the sample that is being observed. From
now on, any movement that will be made on the sample or any change in zoom will have to be compensated
again with a new focus.
If you work in “AF” mode, this operation will not be necessary.

autofocus will be detected.
