General Lens Considerations
There are many lens options to consider, such as focal length, mounting style, and focus locking. The two most critical lens considerations are mounting style and focal length. Banner products use C-Mount lenses only. Before selecting the appropriate focal length, Field of View (FOV) and working distance must be determined.
Banner offers C-Mount lenses of the following focal lengths (in millimeters): 4, 8, 12, 16, 25, 50, and 75. Other manufacturers’ C-Mount lenses may also be used.
The following sections provide a tour through the process of determining the Field of View, working distance, and focal length:

Field of View

Field of view (FOV) is the area of the inspection captured on the camera’s imager. The size of the FOV and the size of the camera’s imager directly affect the image resolution (one determining factor in accuracy). See the illustration below.
NOTE: The PresencePLUS Pro camera imager size is 640 pixels wide by 480 pixels tall.

Determining Field of View

To determine FOV size: Measure the size of the inspection area (inches or millimeters), and allow extra area to accommodate any anticipated movement of the target object.
To verify that the FOV is sufficient for the required resolution:
1. Estimate the required resolution or minimum detection size; for example, will the inspection
measure to a tolerance of 0.1 mm? 1 inch? 10 feet?
2. Use the FOV Formula below to determine the maximum horizontal and vertical FOV that will
maintain the required resolution.
3. Verify that the calculated FOV is larger than the inspection area.

FOV Formula

Required Resolution x 640 pixels = Maximum Horizontal FOV Required Resolution x 480 pixels = Maximum Vertical FOV

Calculated FOV Example

Approximate area of inspection is 3.0" by 3.5". Required resolution is 0.01". For the required resolution, is the area of inspection an acceptable FOV?
Required Resolution x 640 pixels = Maximum Horizontal FOV.
0.01" x 640 = 6.4" Maximum Horizontal FOV.
Required Resolution x 480 pixels = Maximum Vertical FOV.
0.01" x 480 = 4.8" Maximum Vertical FOV.
The Calculated FOV (6.4" x 4.8") is larger than the area of inspection; therefore, a 3.0" x 3.5" FOV is acceptable.
If the calculated FOV is smaller than the desired area of inspection, options are as follows:
Use multiple cameras.
Inspect a smaller portion of the area.
Reduce the resolution requirement.

Determining Working Distance

Working distance is the distance between the back of the lens and the target object.
Camera
Working Distance
Target Object
Some of the key factors that can restrict working distance are as follows:
The minimum working distance of Banner’s standard lenses is about 2.5 inches. Banner’s high-performance lenses and most C-Mount lenses have a minimum working distance of 14 inches (spacers can be used to reduce that working distance).
The lens may need to be close to the target object to avoid light fluctuations.
There may be physical constraints that limit where the camera can be mounted.

Determining Focal Length

Focal length is the distance between the rear nodal point of the lens (the point where the light rays leave the rear of the lens) and the camera’s imager and is specified in millimeters.

Focal Length Considerations

If more than one focal length seems appropriate for the application, consider the following:
Cost: A lens with a shorter focal length is less expensive.
Depth of focus capability: Depth of focus (focus tolerance) is the area in front of and beyond
the optimal point of focus in which the image quality remains acceptable. A longer focal length provides less depth of focus; a shorter focal length provides more depth of focus.
Distortion (see example below): A larger focal length lens provides a less distorted image. Gauging and the pattern matching tools are sensitive to distortion.

Focal Length Formula

NOTE: Working distance and FOV must be known in order to use this formula. See Field of
View on page 1 and Determining Working Distance on page 3.
Focal Length =
Working Distance x Camera Imager Width (Height)
Horizontal (Vertical) FOV
PresencePLUS Pro Camera Imager Width = 4.8 mm. PresencePLUS Pro Camera Imager Height = 3.6 mm.
For Vertical FOV, replace Camera Imager Width with Camera Imager Height.
Example:
What focal length is needed to view a 45-inch wide object from a distance of 200 inches?
200" x 4.8 mm
Focal Length =
= 21.25 mm
45"
The best option is to use a 25 mm lens.
