Swing prism borescopes have a tiny prism at the tip that pivots, or “swings,” to vary the direction-of-view from 45° to 115°. A ring on the borescope body controls the prism direction. The field of- view is either 35° or 50°, so the borescope effectively sees from -5° to 155°. Another ring focuses the borescope, and a third rotates the borescope tube on 340°, sideways in any direction, without turning the body. Inspect Diesel engine mechanics, use Swing Prism Borescopes to examine cylinders, pistons, and valves. Aircraft engine mechanics use the Swing Prism to locate and investigate FOD (foreign object damage and debris) in jet engines.

Associated with our LED lighting sources, they provide powerful lighting in all circumstances. The range is also offered with a powerful zoom which makes it possible to display even more precise details.
