The X axis of the optical chart shows detection range L (mm), and the Y axis shows the camera distance A
(mm). The curves on the optical chart show the relationship between the detection range 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 required and the value “t5.0” shows the case where a 5-mm Extension
Tube is used.
Example
When a 3Z4S-LE ML-5018 CCTV Lens is being used and a detection range of 40 mm is required at the
measurement target, a camera distance of 500 mm and 5-mm Extension Tube are required.
