ABSTRACT:
The present invention relates to an optical coupling between an end of an optical fiber and an end of a lens, which provides a reliable joint with a determined spacing and angular orientation. The optical coupling permits movement of the end of the optical fiber relative to the lens in at least two alignment directions. Advantageously, the present invention permits movement of the end of the optical fiber relative to the end 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 fiber tube/ferrule and the lens are secured within separate sleeves and the sleeves bonded together. The end of the optical fiber and the end of the lens are optically aligned before being secured in place relative to each other.
