Tele-extenders

Tele-extenders increase the effective focal length of the optics that it is used in conjunction with, thus producing higher magnifications in imaging and visual applications. They are similar to barlow lenses in concept, but they have the distinct advantage that they maintain a consistent magnification irrespective of their placement in the optical train.
