Optical unit for coupling light into an optical fiber, has an LED light source array configured as a planar emitter and a smaller area receiver that is coupled to the coupling surface of the optical fiber

摘要

Optical unit for illuminating the input coupling surface of an optical fiber has a hollow body (3) with a narrowing section the surfaces of which are reflecting or refracting. On the larger forward surface of the hollow body is a planar emitter (1), while on the smaller surface is a receiver (2) that is fixed to the coupling surface of an optical fiber. The planar emitter comprises an LED array.
