FIELD: process engineering.
SUBSTANCE: invention serves to produce multilayer planar optical waveguides, particularly, blanks of multilayer optical disks. Proposed device comprises unit to feed polymer materials with different index of refraction. Spinneret assembly made up of distribution plate with feed orifices, at least, two spaced apart spinneret plates and collecting plate with discharge orifice, all said plates being arranged vertically in common case and superimposed. Note here that lateral surfaces of spinneret plates are flat, while collecting plate discharge orifice represents a lot.
EFFECT: device for production of multilayer planar optical waveguide.
