Borescope, Fiberscope or Videoscope Products

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.

Visual Inspection Equipment
For over 80 years, Lenox Instrument Conpany, an American Innovator in visual inspection instruments, has been serving defense, power generation, and manufacturers by solving their most challenging, and often, hostile remote image acquisition.

Mission Statement
From the 1921 invention of the first industrial borescope, to the first borescope used at a nuclear site, to the internal inspection of today's jet engines, or the internal viewing of a furnace, Lenox Instrument Company has always offered the highest quality and broadest range of remote vision instruments to satisfy our customer's most stringent needs.

Corporate Brochure

Borescope Manufacturer
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.

Lenox Videoscope Technology
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.

Fiberscopes - Flexible Borescopes
Lenox fiberscopes have solved some of the world's toughest inspection problems, in some of the most inaccessible and inhospitable places.

Rigid Borescopes
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.

Micro Borescopes
Micro borescopes are 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.

Sectional Extendable Borescopes
Sectional extendable borescopes 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.
