Abstract:
An optical coupling comprisingan optical fibre housing for accommodating at least one optical fibre;a lens for directing a beam of light into the at least one optical fibre and/or for receiving a beam of light from the at least one optical fibre;a first sleeve for accommodating the optical fibre housing;a second sleeve for accommodating the lens, the first and second sleeve having complementary end faces that when contacting one another allow relative lateral movement with respect to the optical axis of the lens and the longitudinal axis of the optical fibre housing when inserted into their respective sleeves so that by laterally adjusting the relative position of the two sleeves a preferred coupling is achievable prior to the sleeves being affixed together, the end face of the lens nearest the optical fibre housing and the end face of the optical fibre being spaced from one another while the complementary end faces are touching; and,two complementary end faces of the sleeves having adhesive therebetween joining the two end faces, wherein the first sleeve and the second sleeve comprise mating portions, the mating portions permitting restricted relative movement of the sleeves in the plane orthogonal to their longitudinal axes.
