This solution realizes six-dimensional adjustment of the optical lens through the above-mentioned parts, and during the rotation adjustment process, the three rotation axes intersect at one point, and the intersection is located at the center of the lens. The center position of the lens always remains unchanged. This feature can ensure that the adjustment results of each dimension are not coupled with each other, greatly improving the precision and accuracy of the posture adjustment; in addition, the driving thread can realize six-dimensional reciprocating and continuous and smooth adjustment of large strokes, and point contact is maintained during the adjustment process. Compared with the previous surface contact guide rail form, the influence of the track processing accuracy on the adjustment accuracy is greatly reduced.

[0062] Specifically, the Z-axis rotation adjustment thread pair can be used to push the lens to achieve deflection, and after adjustment, the position can be fixed using a locking screw. The Y-axis rotation adjustment thread pair can be used to push the lens to achieve tilt, and after adjustment, the position can be fixed using a locking screw. The X-axis rotation adjustment thread pair can be used to push the lens to achieve pitch, and after adjustment, the position can be fixed using a locking screw.
[0063] It should be noted that the above displacement adjustment processes do not interfere with each other and can be adjusted in any order as needed.
[0064] In some optional embodiments, the adjustment accuracy of the present method can be calculated based on the change of the screw from position 1 to position 2 by rotating the thread pair, as well as the pitch of the corresponding thread pair, the distance between the thread pair vertex and the fulcrum, and the rotation angle.
