F440-F Quick Start Guide 2023 2-4 Position the Smart Camera and Set Up Optics • Use the C-Mount Lens Options tables in 2-3-1 , Determining the Optical Setup , to find a C-Mount 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. The illustration below shows approximate skew axis, pitch axis, and tilt axis. Important: Avoid excessive skew or pitch. Maximum skew is ±30° and maximum pitch is ±30° .
