DEVICE FOR THE OPTICAL COMMUNICATION OF LIGHT GUIDES Russian patent published in 1994 - IPC

FIELD: fiber optic transmission systems, fiber optic communication links. SUBSTANCE: device for the optical communication of light guides has spherical lenses, beam-splitting elements made in the shape of plane-parallel plates or prisms with the beam-splitting cover and light guides. The spherical lenses and the corresponding beam-splitting elements connected into monoblocks by means of soldering in the corresponding beam-splitting element of the spherical lens, whose refractive index is more than that of the beam-splitting element at least by 0.03, with the beam-splitting cover being applied to the surface opposite to the soldering one. Besides between the light guides and the corresponding spherical lenses complementary plates can be installed. The latters are connected with the mentioned spherical lenses by means of soldering, with the refractive index of the spherical lens being more than that of the complementary plate at least by 0.03. EFFECT: simpler design. 2 dwg
