Embodiment Construction

[0023] Below in conjunction with accompanying drawing and specific example the present invention is further described, but not as limiting the present invention;

[0024] Such as figure 1 and Figure 4 As shown, the three-dimensional optical adjustment frame of the present invention includes a base plate 1, a mirror base 2, three adjustment screws 3, three adjustment seats 4, and three elastic screw assemblies 5. The elastic screw assemblies 5 are composed of steel balls 7 , stage clip 10, outer screw 8 and micro-movement screw 9 constitute.

[0025] Such as figure 2 As shown, the base plate 1 has a counterbore 112 with a boss 111, and the boss 111 has three V-shaped grooves 14 uniformly distributed along the circumference; the base plate 1 has a through hole 113 in the middle, and the outer wall has a mounting The threaded hole 19 has the mounting hole 15 on the upper end surface 114 .

[0026] Such as image 3 As shown, there are three threaded holes 21 uniformly distr...

Abstract

A three-dimensional optical adjustment frame, which consists of a base plate, a mirror base, three adjustment screws, three adjustment seats and three elastic screw assemblies, wherein the elastic screw assembly consists of steel balls, compression springs, external screws and micro-movement screws constitute. Adjust the elastic screw to control the coarse adjustment and adjustment range of the mirror base. During fine adjustment, the compression spring in the elastic screw provides the restoring force. Rotate the adjusting screw to adjust the front and rear position and two-dimensional angle of the mirror base. The micro-motion screw locks the mirror base to keep it fixed. move.

Description

technical field [0001] The invention relates to the attitude and position adjustment of optical elements, especially a three-dimensional optical adjustment frame, which uses a movable mirror base to adjust the front and rear displacements and two-dimensional angles, and can simultaneously realize large-stroke rough adjustment and small-stroke fine adjustment of optical elements, and the adjustment is completed Can be locked afterwards. Background technique [0002] In the optical path adjustment, the two angles of the optical element and the displacement adjustment of the optical axis direction are generally placed in a two-plate adjustment mount, which is driven and adjusted by a precision thread, and the three driving threads of the two-plate adjustment mount are distributed at right angles; another common adjustment mount It is a three-pull and three-top adjustment frame, which is adjusted by three top screws and three tension screws to achieve angle and displacement adju...
