Borescopes are commonly used in the visualinspection of aircraft engines, aeroderivative industrial gas turbines, steam turbines, diesel engines, and automotive and truck engines. Gas and steam turbines require particular attention because of safety and maintenance requirements. Borescope vs Endoscope Differences What is the difference between borescope and endoscope cameras? As we know now, endoscopes are a kind of borescope. A borescope is an inspection camera or visualinspection device, which enables you to see inside structures and objects or access areas that would otherwise not be visible to the human eye. Whether you use a borescope (rigid borescope) or a fiberscope (flexible borescope) for direct visualinspection depends from a technical point of view on the diameter of the bore hole or access. Flexible borescopes ( micro borescopes) are used for bore holes between approx. The best borescope/endoscopeinspection cameras offer a versatile range of options to help you to inspect problems in hard-to-reach spots, from car engines to sewage pipes. See this excellent piece of kit. This digital borescope can record HD video and take quality photos. VisualInspection with Optical Endoscopes. Visual Testing with Unmanned Aerial Vehicles.Borescopes are used in foundries to inspect the castings, in the metal cutting industry to make sure the bores are burr-free, and also to inspect cavity sealing. Borescopes and endoscopes give you direct visual access to internal structures, helping you tell natural aging from external damage or disease. By inspecting tissues, pipes, or machinery, you can accurately identify whether issues are caused by wear, corrosion, or injury.
