Intersection position, it is ensured that the friendship of the shaft of reflecting mirror (1) mirror surface center and the first rotary cylinder (3) and the shaft of the second rotary cylinder
Point position is overlapped, and is lockked reflecting mirror by cylinder, the folder between the normal direction of the reflecting mirror and the shaft of the second rotary cylinder (4)
Angle is α；
5. assembled first rotary cylinder, the second rotary cylinder and reflecting mirror are assembled in support frame, by screw through propping up
First rotary cylinder is fixed in the first rotary cylinder concave groove by support threaded hole, is prevented between the first rotary cylinder (3) and support frame
Translation；
6. the support frame is fixed on Experimental Optical platform by threaded hole with screw；
7. the second rotary cylinder and the first rotary cylinder are adjusted repeatedly, until the emergent ray of reflecting mirror meets needed for practical optical path
Shooting angle, that is, reach the center of optical element below；
8. the second rotary cylinder is locked by the first rotary cylinder threaded hole with screw, it will by support frame threaded hole with screw
The locking of first rotary cylinder.
Technical effect of the invention is as follows:
1, the present invention can effectively eliminate plane mirror centre bit due to having used a kind of rotary shaft optical adjusting frame to design
The movement set is eliminated and adjusts error.
2, the present invention due to used a kind of rotary shaft optical adjusting frame to design, it can be achieved that light pitching and beat two
Dimension is adjusted.
3, the present invention is due to having used a kind of rotary shaft optical adjusting frame to design, due to being rotation adjusting, rather than it is general
The knob of side adjusts the more convenient adjusting, it can be achieved that in being more compact optical path.
4, the present invention is due to having used a kind of rotary shaft optical adjusting frame to design, due to being that rotation double layer sleeve barrel is adjusted, from
And improve shock resistance.
