• Use the C-Mount Lens Options tables in 2-3-1,
lens that achieves the camera standoff and field of view required for your application. Be sure that the
resulting image resolution is adequate for your application.
• An external light will likely be needed to illuminate the work area where images will be captured. You
can choose lighting from any vendor, including NERLITE or FLV from Omron. NERLITE Smart Series
Illuminators are an example of such lighting. The NERLITE Smart Series Ring Illuminator shown
below left can be used with a Bracket Kit shown below right designed for mounting the Ring Light to
the F440-F.
Note: Refer to the F440-F Datasheet for Ring Light and Bracket Kit options, dimensions, and part numbers.
• If possible, tip the camera relative to the workpiece to avoid the glare of direct specular reflection.
• If your application requires the camera to be oriented perpendicular to the workpieces it will be
inspecting, you can use a Ring Light Polarizer shown below left and a Lens Polarizer shown below
right to avoid the glare of direct specular reflection.
Note: Refer to the F440-F Datasheet for Polarizer Kit and Lens Polarizer options, dimensions, and
part numbers.
• In the case of code reading, symbols can be rotated or tilted at any angle. However, for best results,
symbols should be aligned with the field of view. In the case of linear symbols, aligning the bars in the
direction of movement ladder orientation will minimize image blurring and will result in more
consistent decodes.
Important: Avoid excessive skew or pitch. Maximum skew is ±30° and maximum pitch is ±30°. The
illustration below shows approximate skew axis, pitch axis, and tilt axis.
