Depth of field, hyperfocal distance, and hyperfocal sequence

The depth of field is the distance between the nearest and the farthest objects in an image that appear acceptably sharp.

This white paper describes, in an easy-to-understand way, the depth of field in relation to the hyperfocal distance and the hyperfocal sequence.

Which lens should I use to capture this image

Machine vision requires a photographic lens to project an image of an object onto a camera’s image sensor.
Its selection method is described in our product brochures and on our website as well as in commercially available books and trade journals. However, we receive many questions about the relationship between a field of view (FoV, i.e., the area of the inspection captured on the camera’s image sensor) and a camera’s optical system although it can be calculated very easily.
This white paper gives several examples to plainly describe how to select a camera lens that satisfies your FoV requirement.
