Abstract

"COMPONENTE óPTICO QUE PODE SER UTILIZADO PARA O CORTE A LASER DE UM MATERIAL E PROCESSO UTILIZANDO O MESMO". A invenção relaciona-se a um componente óptico (21), que pode ser utilizado para o corte a laser de um material (26), que compreende pelo menos uma superfície refrativa esférica (22) com o formato para focalizar os raios (30) do feixe incidente sobre um segmento de linha reta (25) situado no eixo óptico (29) do componente óptico (21). O componente óptico (21) é do tipo transmissivo (21) ou do tipo refletivo. Por exemplo, o elemento óptico é formado por uma lente (21) cuja superfície refrativa esférica (22) é definida por um raio de curvatura (24) que varia continuamente com a distância do eixo óptico (29) da lente. O feixe de laser é auxiliado por um gás auxiliar que contém pelo menos um componente escolhido de nitrogênio, oxigênio, hélio, argónio e misturas destes.
