Fiberscopes have articulated tip

Fiberscopes (flexible borescopes) are designed forinaccessible and inhospitable places. The scopes allow for high-resolution inspection to identify flaws down to 0.001 in. For efficient viewing inside complex assemblies, fiberscopes feature a tight bending radius and a totally steerable two- or four-way articulated tip that manipulates around corners, through pipe bends, and past blockages. Diameters range from 3.5 to 10 mm, with lengths to 6 m. Each fiberscope is furnished with a rugged case; a variety of light sources are available.
