Manipulator device for the transfer of laser light into an optical fibre.

摘要

For the transfer of laser light into an optical fibre in such a manipulator device a laser beam (5) is made to form a very finely focused spot of light on the end face of an optical fibre (1,2). In order to obtain an optimal transfer efficiency the manipulator includes firstly a plug member (14) with fibre (1,2) and focusing lens (4) adjustable in the optical axial direction (z-direction) and, secondly, a supporting tube (11) disposed in the z-direction in front of the lens (4) for an optical glas body (12). Said supporting tube is adjustable in x- and y-directions at right angles to the z-axis, against the bias force from a spring ember (21) and angularly adjustable in relation to the z-axis.
