ET-40 Industrial Fiberscope The ET-40 Industrial Fiberscope is a flexible fiber optic inspection instrument designed for remote visual inspection of narrow, inaccessible, and critical areas. Using a coherent fiber bundle, it transmits images directly to the inspector through an optical eyepiece, enabling inspection without dismantling equipment. Its compact 4.0 mm camera diameter, flexible insertion tube, and 2-way articulation make it ideal for inspecting aircraft components, turbines, engines, industrial machinery, and infrastructure. The ET-40 provides a reliable solution for preventive maintenance, troubleshooting, quality control, and internal visual inspections.
