Reinhard, you can make a very nice lense on the end of the fibre optic material simply by bringing it next to a heat source - a soldering iron does a nice job. but don't let the fibre touch the heat source. The longer the exposure, the larger the lense will become (up to a point, of course). Form the lense first, then trim the other end to length. You can use the Kristal Klear or ca to secure it in place.
