focal ratio

焦比

即:放大倍数=物镜焦距/目镜口径 =入射瞳孔直径/出射瞳孔直径 ---------------------------------- 焦比(Focal Ratio) 望远镜放大倍数不能无限制的增加,即目镜不能太短;最短约四毫米,主镜焦距亦不能太长,究竟焦距长度如何决定呢?

focal ratio

焦比(焦距/直径)

Focal Length:焦距 | Focal Ratio:焦比(焦距/直径) | Thickness:厚度(应该是主镜镜片厚度)

nominal focal ratio

标称焦比

nominal deviation 标称偏仪 | nominal focal ratio 标称焦比 | nominal poer 标称功率,额定功率
