CCTV Lens

When using a camera (single) and pattern-lighting, refer to the following table to prepare the lens and macro-conversion ring. The lens may vary from the size of measurement objects and setting distance of camera.

Digital camera (unit) 0.3 Mega pixels Model FZ-S

Digital camera (unit) 2Mega pixels Model FZ-S 2M

*Connecting 5 mm extension tube (Model 3Z4S-LE ML-EXR ) for FZ-LEH25 is not possible.

For high-intensity pattern illumination Model FZD-LT series

How to View Diagram

The horizontal axis of diagram indicates the Sight (L, in mm), and longitudinal axis indicates setting distance (A, in mm). This diagram shows the relationship between Sight for different types of CCTV lens and setting distance. Please verify the types and view diagram given the fact of different lens types. The length of extension tube corresponds to the point of "t5.0" on the diagram. This point is marked with "t0" if extension tube is not employed, and 5mm extension tube is marked with "t5.0".

(Example)

If Sight of measurement objects is 40mm, and 3Z4S-LE ML-5018 CCTV lens is used, the setting distance of camera is set as 500mm, and a 5mm extension tube is required.

Extension Tube

Extension tube, installed between lens and camera, is used to adjust focal distance. Any length can be achieved by combination of 7 tubes.

Table: Extension Tube(Model 3Z4S-LE ML-EXR)
Max. O.D.	Height
O30

Note

0.5 mm, 1.0 mm and 2.0 mm extension tubes shall not be overlapped.
Since it's installed at spiral sections of lens and other extension tubes, overlapping of over 2 tubes will lead to unstable fixation.
Extension exceeding 30 mm shall be enhanced according to different vibrating conditions.
