| 摘要 |
The present invention relates to an optical coupling between an end of an optical fibre and an end of a lens, which provides a reliable joint with a determine d spacing and angular orientation. The optical coupling permits movement of the end of the optical fibre relative to the lens in at least two alignment directions. Advantageously, t he present invention permits movement of the end of the optical fibre relative to the e nd of the lens in a direction perpendicular to the optical axis of the lens, before the optical coupling is secured. The optical fibre within an optical fibre tube/ferrule and the lens are secured within separate sleeves and the sleeves bonded together. The end of the optical fib re and the end of the lens are optically aligned before being secured in place relative to eac h other.
