Fiber inspection during standalone operation Viewing the fiber chamfer
Viewing the fiber chamfer
In Live view, you can visually analyze the fiber chamfer by using the
Chamfer Focus
tool to bring the fiber chamfer
into focus ( Figure 3-1 ). The
CHAMFER FOCUS OFFSET
setting (see “Managing microscope settings” on page 2-15 )
lets you control the amount by which the chamfer is brought into focus each time you apply the
Chamfer Focus
tool. Setting a lower value applies less focus than a higher value, letting you bring the fiber chamfer into focus
more gradually.
Note:
As
Chamfer Focus
is applied, the view of the fiber end face becomes less focused.

Successive applications of the tool after obtaining a focused view of the chamfer will bring the

▪ Tap the touchscreen to hide the Live view tools, and then tap again to show them.
