Abstract
The invention relates to an arrangement for and a method of shaping an end face of an optical fiber . The end face is heated by a heat source in order to form a substantially hemispherical end face , which functions as a lens and has a predetermined radius value. An actual radius value of the end face is repetitively calculated by a control computer using information from an image processing device , which computer then compares the actual radius value with the predetermined radius value. The heating of the end face is continued if the actual radius value is lower than the predetermined radius value, and discontinued if the actual radius value is equal to or higher than the predetermined radius value.
