The invention relates to a spatial light transmission device for laser communication and an adjustment method, belongs to the technical field of optical signal rotation transmission, and solves the technical problems of unstable mechanical structure, complex detection and adjustment processes, insufficient resource utilization and low reliability in a laser communication spatial light transmission process. Through reasonable application of a to-be-measured collimator, an adjustment collimator, a laser, a circulator, a reference prism, a plane mirror, an optical power meter, a theodolite, a six-dimensional adjusting frame and the like, a pointing angle reference and a radial displacement reference of the to-be-measured collimator are respectively transferred to the plane mirror and the adjustment collimator; the influence of mutual coupling of the pointing angle error and the radial displacement error of the collimator on the reading of the optical power meter is avoided, and high-precision measurement of the
