DEVICE FOR PRODUCTION OF MULTILAYER POLYMER OPTICAL FIBER Russian patent published in 2000 - IPC

FIELD: devices for production of polymer optical fiber with different distribution of refractive index for supermode polymer light guide and polymer light guide with gradient of refractive index, both, of focusing type and scattering type. SUBSTANCE: device has unit for supply of polymer materials with different refractive indices and spinneret set. The latter presents a set of several modules vertically arranged on one another in common housing. Each module consists of several distributing plates and one or two gathering plates laid down successively on one another. EFFECT: higher quality of optical fiber due to constant geometric sizes of its layers and eliminated limitation of fiber layer quantity. 10 cl, 9 dwg
