ABSTRACT:
A method for identifying measured quantity proportions for the length difference between an optical element and the envelope for the optical lead when forming an optical lead, which has the envelope loosely receiving the optical element and the method includes extruding the envelope around the element and then passing the lead through at least one cooling path. The speed of the envelope is identified both proceeding as well as following the cooling path, and the desired quantities are formed by different uses of the two measured speeds.
