Wide-range dispersion confocal lens convenient to install

The invention discloses a wide-range dispersion confocal lens convenient to install, and relates to the technical field of optical equipment. The lens specifically comprises a shell and a lens assembly, an emergent light hole is formed in the closed end of the shell, and the lens assembly is arranged in the shell and sequentially comprises a pressing ring, a first spherical lens, a first gasket, a second spherical lens, a second gasket, an aspherical lens and a base from outside to inside. The pressing ring, the first gasket, the second gasket and the base are all in a circular ring shape, a limiting pull rod is arranged on the base, and the limiting pull rod sequentially penetrates through the aspherical lens, the second gasket, the second spherical lens, the first gasket and the first spherical lens and then is fixedly connected with the pressing ring through screws. The lens can well ensure dispersion uniformity, and is simple in structure and convenient to install. 本发明公开了一种方便安装的大量程的色散共焦镜头，涉及光学设备技术领域。具体包括外
