The invention discloses an annular compound lens miniaturized laser transceiver co-aperture device which comprises a fixed casing, an annular compound lens and a detection system module. The annular compound lens is fixed on the front end inside the fixed casing. The detection system module is fixed on the rear end in the fixed casing. The annular compound lens is provided with a circular boss atthe center of the convex surface of the existing convex lens, and the front end face of the boss is a circular convex surface. A convex lens surface composed of a receiving lens part and an emitting lens part is formed. The angle between the axial direction of the annular compound lens and the reflection plane of the reflection mirror of the detection system is 45 degrees. A laser emitting module,an emitting driving circuit, a control circuit and the casing body adopt an electromagnetic shielding structure. The laser transceiver co-aperture device provided by the invention is designed by using the annular compound len
