Abstract

A lens barrel using an optical fiber is provided to remove a scattering phenomenon generated in transmitting a light by using a transparent acrylic. A lens barrel using an optical fiber includes an inner barrel, an outer barrel, an optical cable, a mount(12), a cap(15), and an optical lens(14). The inner barrel is coupled with the outer barrel. The optical cable is installed between the inner barrel and the outer barrel. The mount is coupled to a side of the outer barrel. The other side of the outer barrel is coupled with the optical cap. The optical lens is coupled inside the inner barrel. The optical cable is fixed on a front plane of the barrel(13) to have one to one ratio of an optical input unit to an optical output unit. The optical cable is fixed by using a specific bonding.
