Generation of bottle beam by modulating the spatial coherent coefficient of partially coherent beams is investigated. Based on the theorem of van Cittert-Zernike and scalar diffractive theory, partially coherent beam with particular coherent coefficient is constructed. And focused properties of this kind of partially coherent beam is studied. Based on theoretical results, an optical system to achieve the special partially coherent beams, and focus partially coherent beams with a thin lens is designed. The results indicate that particular partially coherent beams can be converted into bottle beam after focusing by thin lens. Moreover, the influence of parameters of optical system and focus length of thin lens on construction of the bottle beam is studied. The greater of lens focal length an
