Manipulator device for the transfer of laser light into an optical fibre
TLDR
In this article, a plug member with fiber and focusing lens adjustable in the optical axial direction (z-direction) and a supporting tube disposed in the z-direction in front of the lens for an optical glass body is presented.Abstract:
For the transfer of laser light into an optical fiber in such a manipulatorevice a laser beam is made to form a very finely focused spot of light on the end face of an optical fiber. In order to obtain an optimal transfer efficiency the manipulator includes firstly a plug member with fiber and focusing lens adjustable in the optical axial direction (z-direction) and, secondly, a supporting tube disposed in the z-direction in front of the lens for an optical glass body. Said supporting tube is adjustable in x- and y-directions at right angles to the z-axis, against the bias force from a spring member and angularly adjustable in relation to the z-axis.read more
