Abstract
Abstract A device for the coupling of lasers, diodes or the like with one another or with light-conductive fibers or of such fibers with one another, having two support bodies for the holding of a laser, of a diode or of one fiber in the directio of one optical axis. Between the two support bodies, there is positioned an intermediary body which is guided, with one of the two support bodies, in the direction of the optical axis and connected in a displaceable manner by means of sliding surfaces. The contact surfaces extend perpendicularly to the optical axis. By means of the contact surfaces, a precise rotational adjustment of the support bodies is possible. Fluid adhesive material can be placed between the contact surfaces by means of the capillary effect, and thus a very precise fixing of the support bodies and intermediary body, and thus of the optical parts to one another, can thereby be attained.
