CCTV Lenses
When using a Camera without a light (F150-S1A-2D), refer to the following graph to select the
appropriate Lens and Extension Tube. The lens required will differ depending on the size of the
object and the distance to the lens (WD).
Optical Chart
Interpreting the Graph
The horizontal axis of the graph shows the field of vision L (mm), and the vertical axis shows the
working distance WD (mm). The curves on the graph show the relationship between the field of
vision and camera distance for each CCTV lens. The values are significantly different for each
lens, so double-check the model of the lens before using the graph. The values indicate the
lengths of the Extension Tubes. The value “0” shows the case where an Extension Tube is not
needed and the value “5” shows the case where a 5-mm Extension Tube is used.
Example:
When a 3Z4S-LE C1614A CCTV lens is being
used and a field of vision of 10 mm is needed
at the measurement object, a working dis-
tance of 30 mm and 5-mm Extension Tube
are required.
