Abstract:
1. A method for manufacturing a rod with an optical thin film wherein a plurality of rods are integrally fixed with a resin so as to have axes running in parallel to one another, wherein the rods each have a circular cross section and are aligned in parallel to and in contact with one another, and the resin is a thermoplastic resin, the method comprising sequentially performing: forming a rod block by allowing the resin to enter gaps between adjacent rods to thereby fix the rods to one another; cutting the rods into a predetermined length; polishing the cut endfaces of the rods; forming an optical thin film on the polished endfaces of the rods, wherein the resin has a melting point higher than the temperature to which the rods are exposed during said forming; and separating the rods from one another by dissolving or swelling the thermoplastic resin with a solvent to dismantle the rod block after completion of said forming an optical thin film.
