Flexible Type

Flexible borescopes that bend to fit the shape of the pipe or cavity for insertion.

  • The Lightscope's built-in white LED illumination has high color temperature for clearer observation.
  • Angle of view: Approx 60°.
  • Tip diameter: 5 or 8 mm (7.5 or 10 mm when Side-view Adapter is attached)

Flexible Type Lightscope is a lineup of ideal industrial borescopes for inspection and observation of narrow cavities or hollow spaces. The handheld focus adjustment mechanism allows for you to adjust the focus during observation to anywhere between infinity and the minimum focus distance of 10 mm. Pixel counts range from 7,400 to 10,000, and there are four effective lengths available (1,000, 1,350, 2,000 and 3,000 mm). The waterproof head and tube (i.e. the probe) sections enable work in wet environments.

Main Applications

  • Automotive: Engines, transmissions, differentials, air conditioners
  • Industrial machinery: Engines, transmissions, hydraulic pipes
  • Gas equipment: Pipes, vents
  • Aerospace: Turbine blades, combustion chambers, rocket engines
  • Sewers: Plumbing, toilet clogs, defect inspection, residential plumbing
  • Petrochemical plants: Process pipes, plumbing, pressure storage tanks, heat exchangers, boilers
  • Shipping: Boilers, turbines, diesel engines
