The invention relates to a single-component strong-light-shooting double-view-field switching optical system, which comprises a fixed group A, a switching group B, a fixed group C and an imaging target surface which are sequentially arranged from left to right along a light incidence direction, and is characterized in that the fixed group A comprises a biconvex positive lens A-1, a biconvex positive lens A-2 and a biconcave negative lens A-3; the switching group B comprises a crescent-shaped negative lens B-1, a crescent-shaped positive lens B-2 and a biconcave negative lens B-3; and the fixed group C comprises a biconvex positive lens C-1, a crescent negative lens C-2, a crescent positive lens C-3, a biconvex positive lens C-4, a biconcave negative lens C-5, a biconcave negative lens C-6, a crescent positive lens C-7, a biconcave negative lens C-8 and a biconvex negative lens C-9. The optical system is simple in structure and reasonable in design, the optical system can achieve rapid switching of large and s
