A method of aligning an optical fibre with a light source, such as a solid state laser, comprises substantially aligning the axis of optical fibre with the light source and locating two lenses between the fibre and the source. One of the lenses is fixed and the other is movable in a plane perpendicular to the axis of the fibre. The lens is moved until the image of the light source is focussed on to the end of the fibre, the fibre also being axially movable. The method can be termed an "optical lever", movement of the lens causing a smaller movement of the image. The requirement for fixing the fibre or the lens extremely accurately is therefore reduced. |
