description The invention discloses an optical assembly and an optical system. The optical assembly comprises a first cylindrical lens, a second cylindrical lens and a dodging assembly. The curved surface of the second cylindrical lens is perpendicular to the curved surface of the first cylindrical lens. The dodging assembly comprises a plurality of third cylindrical lenses, and the third cylindrical lenses are sequentially connected to form a cylindrical lens array. Through the first cylindrical lens and the second cylindrical lens, convergence of laser in two mutually perpendicular directions can be realized respectively, so that laser shaping is realized. Light uniformizing treatment is achieved through a plurality of third cylindrical lenses, light beams entering each third cylindrical lens in an incident mode are basically uniform, each third cylindrical lens divides incident laser into a plurality of small light beams, and the small light beams are sequentially overlapped on an illumination face to form uniform lig
