- Method for fabricating an optical component (Cnf) that is configured so as to generate on a near field illumination target an illumination that has a determined pattern according to which each point (i) of the illumination target receives a quantity of light (alpha_i) via an illumination originating from an illumination light source which is incident on the optical component (Cnf) placed between the illumination light source and the illumination target, characterized in that the method includes the following steps: (a) positioning an origin point O between the illumination light source and the illumination target; (b) for each point (i) of the illumination target, computing a direction (dir_i) which corresponds to the direction of the vector connecting the origin point O and the point (i) on the illumination target; (c) positioning a reference point A between the origin point O and the illumination target; (d) creating the optical component (Cff) whose surface passes through the reference point A and which, when the illumination originating from an illumination light source is incident on the optical component (Cff), generates an illumination comprised of the all the illuminations of direction (dir_i) and quantity of light (alpha_i); (e) for each point (z_i) of the optical component (Cff) that generates the illumination of direction (dir_i) and quantity of light (alpha_i), computing a corrected direction (dirc_i) which corresponds to the direction of the vector connecting the point (z_i) and the point (i) on the illumination target; (f) determining whether or not, for each point (i), the difference between the direction (dir_i) and the corrected direction (dirc_i) satisfies a predetermined criterion; (g) if, for each point (i), the difference between the direction (dir_i) and the corrected direction (dirc_i) satisfies the predetermined criterion, fabricating the optical component that corresponds to the optical component (Cff), (h) if, for each point (i), the difference between the direction (dir_i) and the corrected direction (dirc_i) does not satisfy the predetermined criterion, reiterating the steps (d) to (f) by substituting (dir_i) with (dirc_i).
