Optical light beam distributor for fibre=optic network - has beam deflector in form of truncated equilateral pyramid between input dispensing optics and output focusing optics

摘要

The optical focussed light beam divider, installed in optical conductor networks, includes one input and several outputs, an input-side beam spreading lens (15), a beam divider unit (7) and output-side focussing lenses (20). The beam spreader and the output-side focussing optics are arranged on the beam divider unit (7). The latter is pyramidal-shaped, and includes an equilateral prism (9) cut into the base (8) of the pyramid symmetrically to the pyramid's axis of symmetry, resulting in reflecting cathetus surfaces (10,11) as well as the outer pyramid surfaces (12,13). USE/ADVANTAGE - Optical branching device, switch, power divider or signal duplicator in light conductor networks. Even distribution of intensity of incident light into several emergent partial beams.
