ABSTRACT:
A process for producing a chalcogenide glass fiber which comprises placing a cylindrical chalcogenide glass preform vertically in a cylindrical crucible furnished with a nozzle in its bottom portion, heating the crucible only at vicinity of the nozzle, and continuously drawing the glass into a fiber with the temperature of the crucible at the vicinity of the nozzle being maintained at such a level that the viscosity of the glass is within the range of 10.sup.3 to 10.sup.7.5 poises.
