Borescopes come in many flavors. NDT looks at a cross section of some of the available products on the market.

For years, the two primary types of industrial borescopes were rigid and flexible borescopes or fiberscopes. The type used depended on the application. While those scopes are still often used, today the market includes video borescopes and other tools for specialized applications. The following is an abbreviated look at some of the borescopes on the market.



Available borescopes

The Series B Rigid Borescopes from AEI North America Inc. features forward viewing direction (0 degree); may add 90 degree mirror tube, and side viewing direction, fixed, with prism. The tools all have focusable, DIN style eyepiece. Models with a 45 degree or 70 degree field of view are available. Reply 30

Flexible fiberscopes from Edmund Industrial Optics feature fiber optic technology to inspect hard-to-reach areas. Semi-rigid sheathed 0.5 millimeter diameter glass fiber imaging bundle enables the scope to bend around obstacles while maintaining shape. Imaging through the bundle occurs because fibers are aligned coherently-both ends retain position exactly relative to each other. It bends repeatedly to a 3-inch radius without damage. A 25X eyepiece offers near-infinite focusing range and wide angle image. Both scopes can work with a C-Mount Video Coupler. Reply 31

Everest VIT's VideoProbe XL PRO Plus video borescope has digital video features including CompactFlash removable storage media, the ability to record and playback more than two hours of DVD format MPEG2 video and a USB streaming digital video port.

It can record digital still images and MPEG2 or MPEG1 video either on its internal 32MB flash memory or on the removable CF cards.
