Abstract

본 발명은 광학기기에 사용되는 렌지의 최종기압 성형전 단계의 프리폼(Preform) 형태를 연삭, 연마 가공공정을 거치지 않은 간단한 성형방법에 의해 성형하는 기술에 관한것으로 용융그라스를 1단계이상의 가열지지대 및 이동통로를 거쳐 글리스 점성이 10°~107.6poise에 해당하는 그라스 프리폼을 자중에 의해 가열변형되도록 하는 광학소자의 글라스 프리폼(Glass Preform)성형방법에 관한 것이다.The present invention relates to a technique for forming a preform of the stage before forming the final pressure of the stove used in the optical apparatus by a simple molding method without a grinding and polishing process, wherein the molten glass is heated in one or more stages. The present invention relates to a glass preform molding method of an optical device, in which glass preforms having a viscosity of 10 ° to 10 7.6 poise are heated and deformed by their own weight through a moving passage.
