Abstract

Patente de Invenção: <B>"POLìGONO CIRCULAR"<D>. Um polígono de formato genericamente circular tendo facetas internas. O polígono tem um corpo feito de um material claro em termos óticos. A luz passa através do corpo e reflete a partir das facetas. O polígono também inclui uma abertura axial central. O polígono é adequado para uso em um conjunto de polígono onde é montado em um eixo motor. O conjunto de polígono é adequado para uso como uma estação de exposição em um scanner de saída de rastreação.
