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.

Lenox sectional borescopes will fit into openings as small as 4 mm, provide working lengths from 12 in. to 1200 in., and deliver resolution to allow identification of flaws as small as 0.0005 in. Probe diameters available include 4, 5.5, 8, 10, 12, 23, 35, 45, and 70 mm. These units are used to inspect tubing, drill pipe, vessels and chambers, chemical reactors, hydraulic cylinders, heat exchangers, aircraft landing gear, radioactive equipment, power generation equipment, process lines, vats, rocket casings, foundations of dams and structures, helicopters, tank cars and much more. And, all units are video and digital adaptable. Today, Lenox offers two types of sectional, extendable borescopes: the Universal Inspector with a fiberoptic light source and the extendable borescope family, with an incandescent light source.

Universal Inspector

The Universal Inspector is a high quality, expandable, fiberoptic borescope system that addresses current and future inspection needs by allowing you to add additional components as needs change. Lenox Universal Inspector will replace up to 18 conventional rigid borescopes with one affordable, convenient, state-of-the-art system. Using this modular system, you can enter through openings as small as 4 mm, go in up to 60 in., and inspect via direct, right angle, forward oblique or retrospective viewing angles with 10º to 85º fields of view and 360º orbital viewing.

The Universal Inspector is a high quality, expandable, fiberoptic borescope system.

Universal Inspector provides a versatile solution of interchangeable components that can be purchased separately as needs change. The heart of the system is the universal eyepiece assembly that includes a universal scope and focus control. Attaching a rotatable objective sleeve (available in right angle, forward oblique and retrospective viewing) completes the system. The system can be quickly expanded and reconfigured by replacing the objective sleeve with one or more thread-on extensions and one of six objective viewing heads.

The Universal Inspector can replace a number of different instruments to provide a complete inspection capability at a significantly lower cost. You can configure a system to meet your immediate needs, then add capabilities by adding in-stock components as your needs change.

Extendable Borescopes

Lenox extendable borescopes are supplied as a complete kit in two models: with a diameter of 23 mm and a working length of 28 in., or with a 35 mm diameter and working length of 53 in. The instruments consist of two sections that are threaded together. When you need to increase the working length, you simply unthread the two sections and add one or more extender sections. By adding extender sections, you can increase the working length up to 1200 in.

Lenox Extendable Borescopes

Each extendable borescope comes complete with probe body and eyepiece with adjustable focus, right-angle viewing head with objective lens (usually 55 field of view, although fields of view from 15 to 180 are available), variable transformer, spare incandescent lamps (a black light attachment is one of many accessories available) and a fitted protective case. Threaded extender sections are available in 36 in. and 60 in., lengths. And, you can choose from five different optional interchangeable viewing heads. All Lenox extendable borescopes are digital and video adaptable.
