A multiple light path apparatus, which may be used for a wireless optical A/V (audio and video) communication system, comprises a lens body LB containing at least one cavity C having a part angular to a receiving and/or transmitting side and said angular part forms a reflective wall RW for incoming or outgoing ray for an optical fibre (OF) sideways arranged to lens body LB. The lens body LB or optical fibre OF may be connected to an LED or photodiode or photodetector PD. The lens body LB with cavity C may be formed by moulding. <IMAGE> |
