Abstract
An optical lens equipped glass fiber is formed by bringing at least one end of a glass fiber into contact with an optical lens forming liquid-like material with the liquid-like material deposited onto the end of the glass fiber in a manner to have a curvature due to its surface tension and, after lifting it up, allowing the deposit to stand for solidification so as to obtain an optical lens on the end of the glass fiber.
Claims11
A method for manufacturing a light transmission glass fiber, comprising a first step of bringing at least one end of a glass fiber body into contact with an optical lens forming hardenable adhesive liquid-like organic compound material;
- and a second step of withdrawing the one end of the glass fiber body to cause the liquid-like material to adhere to the one end of the glass fiber body with a curvature due to its surface tension before hardening, thereby forming an optical lens on the one end of the glass fiber body.
