An Introduction to Borescope Uses
by Stephen Landreaux
This article is focused on the construction of borescopes, their parameters, types and features several interesting buying tips.
The borescope is an optical device which can have either a flexible or rigid tube with an eyepiece on one end an objective lens on the other connected together by a relay optical system, which is surrounded by optical fibers that illuminate the remote object. A borescope allows the person to view a magnifying image of a remote object, which is hard to reach by any other means. Depending on the tube, borescope are divided in two types - rigid or flexible.
Each type has its own unique advantages, so it's hard to point out clearly which is better, as it all depends on the application. Nevertheless, the rigid borescopes are the more popular type, maybe becuase they are cheaper. Their disadvantage is that their body is static and it won't reach all the places you would like to see.
The quality of the image produced by a rigid borescope is higher compared to flexible models, and they are also easier to use and can spot flows as small as 0.001. If we have to sum things up, the conclusion is that you should buy a rigid borescope unless if movement limitations are not a problem (have to be in a straight line). There isn't a universal borescope that combines the advantages of both types, at least not for now. One can't say which type is better, it all depends on the specific borescope use.
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.
You should also make sure that the optical zoom range on your camera goes out to a 350mm or longer telephoto, which is equal to 35mm focal length. For a 3MP camera, a digital zoom with the power of 3x will be fine. Also make sure both the borescope and camera are well supported, so that there is no over-strain on the lens, otherwise they can break.
An endoscopy camera is used to evaluate a patient's health by providing the doctor with clear images (recording video materials) of his internal organs. Author - Stephen Landreaux. Don't reprint this exact article. Instead, reprint a free unique content version of this same article.
