| titleOfInvention | Optical fiber preform manufacturing method, optical fiber manufacturing method, and lens manufacturing method |
| abstract | An optical fiber preform capable of suppressing an abnormality in a refractive index distribution due to an increase or decrease in a refractive index in a central portion when an optical fiber having a graded index (GI) type refractive index distribution is manufactured. A manufacturing method and an optical fiber manufacturing method and a lens manufacturing method using the optical fiber preform. A soot deposition step for obtaining a soot deposit body 1 having a cylindrical side surface 3 by depositing SiO 2 fine particles, and an F diffusion step for diffusing F element 5 from the side surface 3 of the soot deposit body 1. And a sintering process for sintering the soot deposit body 1 that has undergone the F diffusion process. A method of manufacturing a lens by cutting the optical fiber into a lens length.
