Swing prism borescope
max. ø 9 mm Gradient Lens

The Hawkeye Blue Swing Prism borescope has a tiny prism at the tip that pivots, or "swings", to vary the direction-of-view from 16° to 118°. A ring on the borescope body controls the prism direction. The field-of-view is 45°, so the borescope effectively sees from -7° to 133°.

Another ring on the borescope body is used for focus and a third ring rotates the borescope tube over 360°, allowing the user to sweep out a full view of the cavity without turning the borescope body.

Diesel engine mechanics use the Swing Prism borescope to examine cylinders, pistons, and valves. Use the Swing Prism to locate and investigate FOD (foreign object damage and debris) in jet engines.
