be adjusted by sliding the camera forward or backward in actual operation.

First: Start by defining the field of view requirements for each camera. Refer to the diagram at bottom left. The
field of view is considered to be the area or areas requiring inspection. This does not necessarily include the
entire part or object in the field of view.
Second: Determine the camera distance, measured from the object surface to the camera. Refer to the lens setting illustration for
additional information about setting distance. This distance can impose limitations on the field of view and lens choice.
To get the greatest flexibility in lens selection, keep the camera setting distance as flexible as possible.
Third: Using the field of view and camera setting distance requirements, use the optical graph axis marked "Field of view L (mm)"
to find the matching field of view size. Use the optical graph axis marked "Camera distance A (mm)" to find the approximate
camera setting distance. Follow the values across the chart until they cross. Refer to the lens part reference on the right at
the end of the graph line to find the correct lens size. (If a "t" value other than 0 is indicated, corresponding lens extension
tubes will need to be added in between the camera and lens in order to properly focus the image. The "t" value indicates the
thickness of the extension tubes required.)
Note: Extension tube length should not exceed 10% of the focal length of the lens. When looking at other manufacturers’
lenses not referenced by Omron, please use a 1/3-inch CCD size as a selection value reference.
Fourth: If an appropriate lens cannot be found to satisfy your application, please consult your Omron vision representative for
additional assistance in lens selection options.
* Lens diameter does not include lens ring lock screw height.
Note: Omron reserves the right to change lens suppliers and specifications without notification. Please verify all lenses with sales personnel.
