Sectional Extendable Borescopes

As rigid borescopes became widely used, it became apparent that units with a long working length could be a valuable inspection tool in certain applications. However, the problems of transporting and storing very long optical instruments presented a number of logistical problems. To meet this need, Lenox Instrument introduced the concept of a sectional, extendable borescope. These units are modular in design and allow the user to add extender sections to provide very long working lengths. Originally developed in 1920 to inspect huge steam turbines, Lenox sectional borescopes were adopted by the U.S. Army during World War II to inspect gun barrels. Today, they are the industry standard for applications where uncompromising image quality and user control over length are critical. No other rigid borescope delivers such exceptional image resolution with this much length adaptability.
