 Accordingly, the fiber flange is determine like the aforementioned foundation plate of an adjusting sleeve, but an ocular fiber is permanently ride in the central opening. 
 When setting the proportion of the light output signal that is coupled into the optical fiber, use is therefore made of the fact that the light - emitting device contains a semiconductor device laser which emits a beam of radiation sickness with a defined direction of polarization. The angular position of the polarization filter therefore determines the transmitted proportion of the balance beam of radiation through the polarization filter, and therefore the proportion of the radiation coupled into the optical roughage. 
 In accord with an added object of the invention, there is provided a method of assembling a fiber - optic convey component.
