Basically the same arrangement as of collimating optics (474 1036) but with a fine adjustment holder with four axes and an objective of smaller focal length to focus the collimated laser diode radiation in such a way that an effective coupling to the fibre is ensured. Purposely a beam shaping of the laser diode radiation has been omitted to simplify the entrance into the experiment.

• Microscope objective: 10x, NA = 0.25
