WebThe distance from the lens to the focal point is called the focal length. For converging lenses, the focal length is always positive, while diverging lenses always have negative focal lengths. However, these conventions are arbitrary, and physicists could just as easily have made the signs opposite.

For a thick lens (one which has a non-negligible thickness), or an imaging system consisting of several lenses or mirrors (e.g. a photographic lens or a telescope), there are several related concepts that are referred to as focal lengths: Effective focal length (EFL) The effective focal length, also sometimes called … small o gauge railroad layoutshttp://physics.bu.edu/~duffy/PY106/Reflection.html highlight fachmagazinWebBy definition, the focal point of a lens is the point where two or more rays parallel to the principal axis gets focused.
