Cylindrical lens is irreplaceable in the field of beam manipulation, which can generate new types of light field by diffraction effect, providing possible tools in micrography, optical micromanipulation and biomedicine field in future. The diffraction light field distributions of the Bessel beam and bottle beam passed though a cylindrical lens are studied in this paper using both experiment and simulation methods. In terms of simulation, Collins formula, combined Huygens Fresnel diffraction integral formula and optical matrix, is used to calculate the diffraction patterns. Specially, the thickness and refractive factors of the lenses in the optical system are introduced into the matrices in this paper, so that the lens is no longer approximated as a thin film, and the bottle beam diffracted by a cylindrical lens is first studied. The simulation and experimental images are broadly consistent for both those two diffraction phenomena.

柱面透镜在光束操纵领域具有不可替代的作用，它可以通过衍射效应产生新型的光场，为未来显微摄影、光学显微操纵和生物医学领域提供了可能的工具。本文采用实验和仿真方法研究了通过柱面透镜的贝塞尔光束和瓶光束的衍射光场分布。在模拟方面，采用柯林斯公式，结合惠更斯菲涅耳衍射积分公式和光学矩阵，计算衍射图样。具体来说，本文将光学系统中透镜的厚度和折射因子引入矩阵中，使透镜不再近似为薄膜，首先研究了柱面透镜衍射的瓶光束。这两种衍射现象的模拟和实验图像大致一致。
