Description
剛性円筒状外壁および可撓性内壁を有する装置を用いて光ファイバプリフォームを作製した。剛性円筒状外壁を、6インチ(15.24cm)の内径、46インチ(116.84cm)の長さ、および1/2インチ(1.27cm)の壁の厚さを有する鋼で作製した。可撓性内壁は、応力が加えられていない状態で約4.25インチ(10.795cm)の直径を有するウレタンゴムチューブであった。ウレタンゴムチューブの頂端部および底端部を鋼円筒の頂端部および底端部にクランプした。さらに装置は、頂部および底部アルミニウムエンドキャップを備え、各エンドキャップは約1インチ(2.54cm)の厚さと、半製品プリフォームに対応する中心孔と、ねじ付きロッドを通すための4個の周縁孔とを有した。可撓性内壁の外径が剛性外壁の内径と本質的に同じになるように、可撓性内壁と剛性外壁との間の空気を実質的に取り除いた。剛性円筒の内径とほぼ同じ直径を有する8インチ(20.32cm)の発砲体栓を円筒の底部と同一平面となるようにキャビティ内に挿入した。次に円筒の底部をアルミニウムエンドキャップおよびViton Oリングでシールした。
