What is boroscope?

A boroscope is an optical instrument used for inspecting hard-to-reach areas that cannot be seen directly. It consists of a long, thin probe with a lens at the tip, which can be inserted into small spaces. The lens is connected to an eyepiece or a camera, which allows the user to view the internal working of objects or machinery that are otherwise impossible to inspect.

Boroscopes are commonly used in aviation, aerospace, automotive, and industrial applications for inspecting engines, turbines, pipes, and other machinery. They are essential tools for maintenance and repair work as they can detect hidden defects, corrosion, or damage that might otherwise go unnoticed.

Modern boroscopes use fiber-optic technology, which enables illumination of the inspection area without requiring direct light. The image is transmitted through a bundle of fiber-optic cables to the eyepiece or a camera screen.

Overall, boroscopes are valuable assets for engineers, technicians, and mechanics in identifying and diagnosing issues in even the most inaccessible parts of a system.
