CCTV Lenses
When using a Camera without a light (F150-S1A or F160-S2), refer to the following graph to select the
appropriate Lens and Extension Tube. The lens will differ depending on the size of the measurement
object and the distance from the Camera.
Optical Chart
Understanding the above chart
The X axis of the graph shows field of vision L (mm), and the Y axis shows the camera distance
A (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 "t" values indicate the lengths of the
Extension Tubes.The value "t0" shows the case where an Extension Tube is not needed and the
value "t5.0" shows the case where a 5 mm Extension Tube is used.
Example:
When a 3Z4S-LE ML-2514 CCTV
Lens is being used and a field of
vision of 40 mm is needed at the
measurement object, a camera
distance of 300 mm and 1 mm
Extension Tube are required.
