Question: 1 / 400

What does a wide angle of view in a bore scope provide?

Illumination

High magnification

Shorter depth of field

Greater depth of field

A wide angle of view in a bore scope enhances the greater depth of field because it allows the viewer to see a larger area in focus at one time. This means that both near and far objects can be captured clearly within the same field, making it easier to inspect larger surfaces or areas without needing to adjust the focal length frequently. This capability is particularly important in visual testing applications, where being able to assess the entirety of a specific section is crucial for accurate evaluations.

As a result, the ability to maintain a greater depth of field allows inspectors to work more efficiently and effectively, as they can focus on broader contexts without losing clarity on objects at varying distances within the scope's field of view.
