About Lenses

When using a camera (single), refer to the following tables to prepare the lens and extension tube. The lens may vary depending on the size of measurement objects and the camera setting distance.

The horizontal axis of the diagram indicates the Y field of view (mm), and longitudinal axis indicates camera setting distance (mm).This diagram shows the relationship between the field of view of lenses and the setting 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 the field of view of measurement object is 40 mm, and a 3Z4S-LEML-5018 lens is used, the camera setting distance is set at 500 mm, and a 5 mm extension tube is required.

Extension Tube

An extension tube, which is installed between lens and camera, is used to adjust focal distance. Different combinations of the 7 tubes can be used to achieve any desired thickness.

Note
  • Do not overlap the 0.5 mm, 1.0 mm and 2.0 mm extension tubes.
    Since these lenses are installed between the lens and the threaded section of another extension tube, overlapping of 2 or more of these tubes will cause unstable fixation.
  • When a close-up exceeds 30 mm, reinforcement is necessary depending on the amount of vibration.
