Abstract
PURPOSE:To introduce condensed light to an optical cable with low cost, by connecting an optical conductor cable having almost equal diameter as the diameter of quartz core of optical conductor to another end of optical conductor consisting of quartz core and quartz clad layer after alignment. CONSTITUTION:An optical conductor 10 consists of a quartz core 11 and a quartz clad layer 12 coating it, and when an optical energy L condensed with an optical system lens is made incident to one end 10a of the optical conductor 10, if a ratio of a diameter (a) of the quartz core 11 to the diameter (b) of the quartz clad layer 12 is a specific value (from experiences, b/a 3), the optical energy incident to the quartz clad layer 11 progresses the quartz core 11 and that incident to the clad layer 12 is refracted to the center with the layer 12 and finally progresses the quartz core 11. Most of optical energies are outputted from the quartz core 11 at another end 10b of the optical conductor 10. Thus, the solar energy condensed with the lens system is condensed by the optical conductor 10 and introduced to the optical conductor cable with a small diameter.
