A Swing Prism Borescope is a type of rigid industrial inspection scope that features a small, movable prism (mirror) at the tip of its optical or video probe. By manually or remotely rotating this prism, the inspector can change the viewing direction—typically between a straight-ahead (0°) and a side-view (90°) perspective—without moving the insertion tube itself. This allows for a more comprehensive inspection of internal components like engine cylinders, pipes, and castings from multiple angles with a single insertion, improving inspection efficiency and reducing the need for multiple tools or probe withdrawals.

  • Rigid or semi-rigid probe with a movable prism at the tip for directional viewing (e.g., 0° to 90°).

  • Allows inspection of side walls and forward surfaces without repositioning the scope.

  • Used in automotive (engine cylinders), aviation (turbine blades), and industrial pipe inspection.

  • Available in both optical (direct view) and video (digital image) models.

  • Enhances inspection versatility and reduces time spent on internal examinations.

  • Manufactured by various industrial inspection equipment companies worldwide.

Inspect from multiple angles with one tool. Utilize a Swing Prism Borescope for efficient and comprehensive internal visual inspection.
