How to Use Borescopes for Internal Visual Inspection By Dr. Douglas Kindred, President and Chief Scientist, Gradient Lens Corporation Fast, reliable, internal visual inspection is an irreplaceable quality assurance procedure for manufacturers of mission-critical parts and assemblies from fuel and hydraulics systems to vital medical parts. The process starts with selecting the right borescope for the specific inspections you need to conduct. Diameter, length, and direction-of-view are key factors, as is the selection of a rigid, flexible, or video borescope. The following will start you in the right direction. RIGID AND FLEXIBLE BORE SCOPES Rigid Borescopes Rigid Borescopes have superior sharpness and detail because they use traditional glass optics. Choose a Rigid Borescope when the entry path is straight. Rigids have better image quality, and are more durable and less expensive, than flexible scopes. Flexible Fiber Optic Borescopes Flexible Borescopes use optical glass fibers to relay the image. Resolution depends on the number of fibers and their diameter. Each fiber forms a pixel in the final image. When your entry path is curved, you’ll need a Hawkeye® Classic, Pro, or Blue Flexible Borescope. Flexible Borescopes can also offer 2- and 4-way articulation. VIDEO BORE SCOPES Portable Video Borescopes Our newly redesigned, fully portable, Hawkeye® V2’s are brighter, have higher resolution, and are more durable than most comparable videoscopes on the market today. The Hawkeye V2 is available in diameters of 4 and 6 mm, offers 4-way articulation, and is priced starting at $8995. The V2 can also easily capture photos, and video footage, for storage, documentation, or email transmission. Made in the USA. Benchtop Video Systems Any Rigid or Flexible Hawkeye® Borescope can be connected to our Luxxor® Video Camera, effectively making any Hawkeye borescope a portable videoscope! Your borescope can then connect to any laptop or desktop computer, or video monitor, allowing for on-screen viewing, computer storage, and documentation. Inspection video footage, and still images, can be archived, or sent to others via email. For repetitive inspection of parts, you can also add a Hawkeye® Video Slide* to hold the part, and borescope, in a fixed, but easily adjustable, position during inspection. BORESCOPE APPLICATIONS METAL MACHINING & EDM Metal machinists can inspect for burrs, defects, surface finish irregularities, and more, even inside deep or narrow bores. WELDING The quality and integrity of any weld, even in long tubes or complex parts, can be quickly evaluated. CASTING Quickly check for voids, sand and other defects even inside complex castings.
