When you purchase Lenox Borescope, Fiberscope or Videoscope products, you are assured of the highest quality remote visual inspection (RVI) tools. Lenox FireSight High Temp Furnace / Boiler Cameras provide a direct view of your burner, furnace, boiler, kiln or incinerator which helps improve combustion performance, reduce NOx, flame impingement and speeds up boiler start-up and diagnostics.
Lenox Instrument high-temperature camera systems provide clear, crisp images of the combustion process in boilers, furnaces, kilns, incinerators and other combustion chambers. With the real-time image provided, operators can monitor the proper flow of fuel and raw materials, reduce emissions, reduce fuel consumption, speed up boiler light off, and improve safety. Our FireSight products include Air Cooled Firesight Systems, Water Cooled Firesight Systems and Lenox/Pultz High-Temp. Video Camera Systems.
Borescope Products
Lenox Instrument has been a U.S. manufacturer of borescopes since 1920. We are one of the few, if not the only, manufacturer with our own in-house lens grinding and lens production facility. This allows us to control and maintain the highest quality optics to assure you of the brightest, clearest, true-color images, whether seen through an eyepiece, captured on film, or transmitted for viewing on a remote monitor while offering the best prices in the industry.
Videoscopes
Imagine a miniature TV camera mounted on the end of a very flexible fiberoptic cable that you can steer around obstacles and into the smallest cavities. Now, add the ability to view the image from that camera on a bright, clear monitor. These are the inspection capabilities the Lenox Videoscope brings to you, at a very affordable cost.Lenox videoscope technology lets you enter openings as small as 5 mm, go in up to 540 in., enjoy a bending radius of 100 mm and view the image with resolution of 450 lines horizontal. You will be able to easily and affordably inspect welds, seams and joints, search for corrosion, blockages, deposits, loose parts and debris, observe valve and actuator operation, and view deep inside tubing, piping, heat exchangers, castings, boilers, turbines and fuselages of aircraft.
Felxible Fiberscopes
Lenox fiberscopes have solved some of the world's toughest inspection problems, in some of the most inaccessible and inhospitable places. Over the years, we've developed and refined fiberscope technology and taken it to the limit of what optical technology will allow. Rigid Borescope
Lenox has developed what may be the world's most extensive lines of quality, high performance rigid borescopes. To achieve consistently superior performance, we employ computer-designed optics, stainless steel or aluminum construction, sophisticated in-house lens grinding techniques and highest efficiency coatings throughout the optical path. Optical systems are designed to produce an abundance of near-100%-white light and the highest possible resolution. All feature the highest intensity fiber optic illumination. Micro Borescopes
These miniature borescopes are available with diameters as small as 0.5 mm. They deliver a clear, bright image from inside hypodermic needle tubing, through tiny vent holes in turbine blades and within miniature electronic assemblies. Both flexible and semi-rigid models are available, in lengths up to 600 in. Sectional 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. Borescope Accessories
Firesight Products
Lenox Instrument high-temperature camera systems provide clear, crisp images of the combustion process in boilers, furnaces, kilns, incinerators and other combustion chambers. With the real-time image provided, operators can monitor the proper flow of fuel and raw materials, reduce emissions, reduce fuel consumption, speed up boiler light off, and improve safety.
Air Cooled Firesight
FireSight also has a proven record of reliable performance that is unmatched by any other system available today. Lenox manufactures all critical components, including the grinding and polishing the lenses in the company's own optical shop. The system features quartz optics that withstand temperatures up to 1200°F higher than the glass lens used in other systems. The compressed air cooling system provides reliable performance while using considerably less air than competing systems. The rugged furnace lens/periscope assembly has been proven reliable in hundreds of applications and, in fact, tests show it will survive far longer than competing systems in the event of a coolant interruption. water Cooled Firesight
These systems use a water-jacketed furnace lens assembly in place of the air-cooled assembly and wall box, allowing operation in temperatures up to 3800°F. This lens assembly is also slightly smaller than the wall box and can be used in boiler wall penetrations as small as 2-1/8 in. FireSight water-cooled systems provide the same features and reliable performance as air cooled systems for higher temperature applications or for installations where compressed air cooling might be less desirable. Units are available up to 12 feet in length. Lenox/Pultz High-Temperature Video Camera System
These high-temperature video cameras are designed to be mounted directly through the wall of a furnace or other combustion chamber. The camera housing mounts in a 6.4 in. diameter opening and employs triple-wall laminar flow for efficient water cooling of the camera in applications up to 4250°F.
