Both borescopes and endoscopes are instruments used for visual inspection in hard-to-reach areas, but they differ in their applications and design.

    A borescope is typically used to inspect engines, pipes, and other equipment where the inspection area is not easily accessible. Borescopes are typically longer and more rigid than endoscopes, and are designed to be inserted into small openings and narrow spaces to inspect internal components. They can also be equipped with lighting and cameras to capture images and videos of the inspection area.

    An endoscope, on the other hand, is primarily used in medical procedures to view the inside of the human body. Endoscopes are typically flexible and can be inserted through natural openings such as the mouth or anus, or through small incisions in the skin. They can also be equipped with cameras and lighting to capture images and videos of the internal organs or structures.

    In summary, borescopes are used for inspecting hard-to-reach areas in equipment and machinery, while endoscopes are used for medical procedures to view the inside of the body. Borescopes are typically longer and more rigid, while endoscopes are more flexible and designed for insertion through natural openings or small incisions.
