What are Fiber Optics
... On the basis of number of modes:on the basis of number of modes of propagation the optical fiber are classified into two types: (i) Single mode fiber (SMF) and (ii) Multi-mode fiber (MMF) Single-mode fibers – in single mode fiber only one mode can propagate through the fiber. This type of fiber ha ...

Optical aberration
.svg?width=300)
An optical aberration is a departure of the performance of an optical system from the predictions of paraxial optics. In an imaging system, it occurs when light from one point of an object does not converge into (or does not diverge from) a single point after transmission through the system. Aberrations occur because the simple paraxial theory is not a completely accurate model of the effect of an optical system on light, rather than due to flaws in the optical elements.Aberration leads to blurring of the image produced by an image-forming optical system. Makers of optical instruments need to correct optical systems to compensate for aberration.The articles on reflection, refraction and caustics discuss the general features of reflected and refracted rays.
