Fiberscope
A fiberscope is a flexible bundle of fiber optic cable with an eyepiece attached to one end. A fiberscope is used to examine small components in tight quarters. The scope is often used when the part that needs repair can not otherwise be accessed.
The lens on a fiberscope is most often wide angle. Some higher end scopes use and extra fiber optic cable to deliver additional viewing light to the source. All scope will distort the image somewhat. Some specialized fiberscopes can be up to 250 feet long.
Fiberscopes are often used in medicine, computer repair, safe or lock cracking, for forensic work on for surveillance (you have probably seen countless fiberscopes in the movies).
Some fiberscopes we recommend include:
