Swing-Prism Rigid Borescopes

Swing Prism rigid borescopes, by GE, can fulfill the function of two or three separate conventional borescopes.

The direction-of-view is adjustable from 55° to 115° and scans an object’s entire length. A zoom feature magnifies the entire image, unlike conventional zoom features that simply narrow the field-of-view. Additionally, the rotating barrel allows 360° viewing without moving the body of the scope.

Swing Prism borescopes are available in 6, 8 and 10 mm diameters.

Swing-prism Rigid Borescope with Rotation and Zoom Ocular

Swing-prism Rigid Borescopes come with variable direction-of-view, a focusing device, rotatable objective tube and an optional variable magnification zoom eyepiece. Providing the capability to view steplessly in a range of directions, from 55º forward-oblique to 115º retro-view, one instrument can function in the place of two or three separate conventional Rigid Borescopes. This multiple viewing capability is further enhanced by the rotatable insertion tube, which provides 340º of rotation stop-to-stop. (360˚ effective viewing with overlap from field-of view)

This versatility allows the same scope to be used for multiple applications and reduces inspection time by removing the need to stop the inspection to change scopes.

GE Swing-prism Rigid Borescopes are available in three diameters, 6.0 mm (0.24 in.) 8.0 mm (0.31 in.) and 10.0 mm (0.39 in.). On all models, two alternative fields-of-view are available, the standard 56º FOV being supplemented by an optional narrow-angle 35º FOV, giving higher magnification.

An optional variable magnification zoom eyepiece can be selected on the 8.0 mm (0.31 in.) and 10.0 mm (0.39 in.) instruments, making the Swing-prism Rigid Borescope one of the most versatile Rigid Borescopes around, offering variable direction-of-view, variable focus, variable magnification and circumferential rotary scanning.
