To know if a camera can measure a target at a certain distance some calculations can be done.

We have a utility called the FoV calculator which is available on this site, access it by following the procedure below:

1. Go to Download Datasheet and select a camera series
2. Click the FoV Calc. hyperlink for a camera–lens combination. This displays the FoV calculator.
3. To select a different camera–lens combination for a particular camera, select the new combination in the drop-down menu.

The FoV calculator displays the following results:

• HFOV: horizontal field of view in meters and feet.
• VFOV: vertical field of view in meters and feet.
• Depth of field—far limit in meters and feet.
• Depth of field—near limit in meters and feet.
• IFOV: instantaneous field of view in millimeters and inches.
• Distance to target in meters and feet.

Tips

• Each camera may have interchangeable lenses. If this is the case, you can choose a lens from the drop down menu.
• You can switch between metric or imperial units using the drop-down menu.
• Type in several distances separated by commas to calculate the FoV at all desired distances.
