is constant and consistent (unchanging over
time,
no shadows or hot spots)
• Capture the shape and form of the target object with
lighting
that
optimizes
its contrast and separates the feature of

The focus number is a number between 1 and 255. Use the Image pane to determine when the image is sharp enough, or
use the focus number as a guide. Turn the focus ring on the lens
until
the focus number is at the highest possible number
between 1 and 255. The focus number is also available on the sensor display.
Note: There is no
optimal
value for this number, but it can be used as a guide if you are
setting

sensor that are focused on the same target.
e) Tighten the locking thumbscrews to secure the lens at the desired focus.
