Abstract

MéTODO PARA FABRICAR UMA PREFORMA óTICA POR MEIO DE UM PROCESSO DE DEPOSIçãO DE VAPOR INTERNO, BEM COMO UMA PREFORMA OBTIDA COM ISTO. A presente invenção refere-se a um método para fabricar uma preforma ótica por meio de um processo de deposição de vapor interno, no qual é feita utilização de uma fonte de energia e de um tubo substrato, no qual a fonte de energia é móvel sobre o comprimento do tubo substrato entre um ponto de uma inversão no lado de suprimento e um ponto de uma inversão no lado de descarga.
