Methods for optical connection of an optical element, e.g., an end portion of an optical fiber, to a lens
Реферат: A method for optically connecting an optical element, including glass, for example an end portion of an optical fibre (2) having a core consisting of glass, to a lens (4) consisting of glass. The optical element and the lens are fixed in a connector element (14) in a predetermined position in relation to each other and the surface of the lens facing the optical element is treated with an anti-reflection agent (22), for example magnesium fluoride. The thickness of the layer of the anti-reflection agent is adapted with regard to the refractive index of the glass of the optical element, the refractive index of the glass of the lens and the wave length of the light which is transmitted through the system so that the light transmission of the optical connection will be as high as possible and so that the reflections in the connection are thereby as low as possible. <IMAGE>A method for optically connecting an optical element, including glass, for example an end portion of an optical fibre (2) having a core consisting of glass, to a lens (4) consisting of glass.
