A short overview of fiber optic bundles

Numerous spectroscopic applications need more than a simple optical fiber patch cord. Therefore, fiber optic bundles are considered to be the most suitable when it is necessary to measure different simultaneously or those that need an improved signal to noise ratio (as in the case of weak signals). To be more precise, a fiber optic...
