The borescope is an optical device featuring a rigid or a flexible tube with an eyepiece on one end, an objective lens on the other linked together by a relay optical system in between. Such tools find application in inspection jobs where a given area has to be inspected but are inaccessible by other means. Borescopes are either flexible or rigid. Both types of borescopes have their unique advantages (as well as disadvantages), making them suitable only for certain situations. Rigid borescopes the perfect tool for specific tasks, like inspecting automotive cylinders, fuel injectors, hydraulic manifold bodies and gunsmithing. Flexible borescopes can be used to access cavities which are around a bend, as oppose to rigid ones, that have the limitation that access to what is to be viewed is a straight line. Rigid borescopes produce images of higher quality, compared to flexible models, they are also easier to use and can identify flaws as small as 0.001. Bottom line is that unless the limtited movement is not a problem, it's always better to buy a rigid one. As you can see, there is no universal borescope, that is ideal for all tasks. It's not about choosing rigid or flexible, but about buying the best rigid and best flexible borescope and use according to the situation. The conclusion is the when choosing a borescope to buy, you must have a clear idea where exactly you will be using it. Once you know the type, then you have to choose the diameter, so that the borescope will be able to enter the smallest hole required. It's always best to plan for some degree of free movement, that's why get a slightly smaller diameter than the allowed minium. The mangnification of a borescope is a measure of how large and object appears when viewed through the borescope as compared to its actual size when viewed from the same location without the borescope. But the power of magnification doesn't increase automatically if the object that's being viewed moves further away. Borescopes can be used with a digitam camera in order to record the images or view them on a big monitor. Compatibility (borescope-camera) can certainly be an issue here. No one can guarantee if a particular digital camera will work satisfactorily with your borescope, unless it is explicitly stated in the official manual of the device. If you want the borescope image to fill a reasonable portion of the screen, then you need an objective lens with long focal length. The focal length on the camera must be at least 35mm. If you have a 3 megapixel camera, then a 3x digital zoom will be fine. And because cameras are not originally designed to support a borescope, make sure there is no over-strain which can lead to structural damage of the devices.
