The Lenox Fiberscope (flexible borescope) is designed to handle tough inspection problems in highly inaccessible places. It is suitable for inspection of engines, equipment, tubing, pipes, castings and other hard-to-access cavities. The scope allows for high-resolution inspection to identify flaws as minute as 0.001 in (0.025 mm). The fiberscopes have a tight bending radius and a totally steerable 2- or 4-way articulated tip that allows easy manipulation around corners, though pipe bends and past blockages. Diameters range from 3.5 to 10 mm (0.140 to 0.395 in.) with lengths to 6 m (18 ft). All scopes are waterproof, as well as digital- and video-adaptable.
