CCTV Lenses

When using a Camera without a light (F150-S1A or F160-S2), refer to the fol-
lowing 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

The values in the following chart are approximations, and the Camera must be
adjusted after it is mounted.
The horizontal axis of the diagram indicates the Y field of view (mm), and ver-
tical axis indicates camera installation distance (mm) or working distance
(mm). This diagram shows the relationship between the field of view of lenses
and the installation distance for different types. Make sure to verify the lens
type when checking the graph as the field of view value is different for each
type. Points such as "t5.0" on the graph correspond to the thickness of the
extension tube used. "t0" is used if an extension tube is not necessary, and
"t5.0 is used if a 5 mm extension tube is used.
Example
If you use a 3Z4S-LE SV-2514V CCTV Lens for a measurement object that
requires field of view of 40 mm, the camera installation distance must be 300
mm and a 2 mm extension tube is required.
