A light distributor which is connected to an incoming light guide and a plurality of outgoing light guides for distributing a light arriving from the incoming light guide into the plurality of outgoing light guides characterized by the distributor comprising a disk member, which may be circular, of a material which has properties of a low absorption and low scattering, and the member has an abutting surface for both the incoming and outgoing light guides with the abutting surface of the incoming light guide being opposite to the abutting surface of the outgoing light guides. The disk member of the light distributor will have a thickness equivalent to the diameter of the cores of the light guides. The disk member may be of a material which is birefringent or which has a controllable index of refraction.
