Borescope Field of View - What? Why? How?

Borescope field of view
It is important to understand some terms when choosing the right inspection tool - borescope. The field of view (FOV) is the angular extent of the observable inspection area that is seen at any given moment. Borescopes, fiberscopes, videoscopes and other remote visual inspection equipment should all list field of view in their specifications.
A wide field of view allows conducting a turbine inspection to complete each section in one pass while a narrow field of view may require the inspector to inspect the same section of turbine blades twice and take more time to conduct the inspection.
It is also worth attention to evaluate how a different field of view affects the depth of field (the distance from the target a clear image can still be seen). Typically, the wider the field of view a borescope has, the shorter the depth of field.
