Abstract

本发明公开了一种高光通量Halpha波段超广角镜头,包括前透镜组、后透镜组,光阑位于前透镜组和后透镜组之间,前透镜组中透镜L1为负弯月形透镜,透镜L2为负双凹透镜,透镜L3为双凹负透镜,透镜L4为双凸正透镜,透镜L5为双凸正透镜,前透镜组的组合焦距f-前为60.878±2mm,后透镜组中透镜L6为双凹负透镜,透镜L7为双凸正透镜,透镜L8为双凸正透镜,透镜L9为双凸正透镜,透镜L10为双凸正透镜,后透镜组的组合焦距f-后为88.576±2mm,窄带滤光片放置在光阑位置。本发明的高光通量Halpha波段超广角镜头相较于传统的广角镜头具有4倍通光能力,且视场内像质均匀,各视场的光线入射滤光片上角度相近,更适合于带滤光片的窄带成像。
