Problems solved by technology
[0003] In order to overcome the problem that the existing plane mirror placement device will either cause large deformation to the plane mirror and cannot meet the requirements of use, or can meet the requirements but at a high cost, the present invention provides an adjustment mechanism, which can make the plane mirror produce only a small deformation, and can also be adjusted with high precision, which can make the plane mirror quickly enter a stable state

Embodiment Construction
[0019] exist figure 1 In the embodiment shown, a microcrystalline flat mirror 1 with a diameter of 600 mm is placed on a thin steel strip 2 with a thickness of 0.5 mm, and is hung on the main structure 10 by a hanging block 4 and a half-threaded bolt 5 of M14, and the lateral thread adjustment is adjusted. The rod 6 is against both sides of the plane mirror 1, the loosening adjustment screw 7-1 and the tightening adjustment screw 7-2 are used in combination to make the tension steel belt 7-3 pull the plane mirror 1, and the back threaded adjustment rod 8 is adjusted to withstand the plane mirror 1, Adjust the bottom threaded adjustment rod 9 to realize the adjustment of the plane mirror 1 in the up and down and pitch directions.

The invention discloses a shock absorption and adjustment mechanism of a plane mirror. The plane mirror is suspended on a main structure through a thin steel strip and a half-thread bolt, and the functions of shock absorption and high-precision adjustment for the plane mirror are achieved through a lateral threaded adjusting rod, a back adjusting mechanism, a back threaded adjusting rod and a bottom threaded adjusting rod of the plane mirror. The shock absorption and adjustment mechanism has the advantage that under the condition that the plane mirror deforms slightly, the plane mirror can be stable fast through the high-precision adjusting mechanism.
Description
technical field [0001] The invention relates to a plane mirror adjusting device, in particular a mechanism capable of shock absorption and high-precision adjustment of the plane mirror, and the deformation caused by the device to the plane mirror meets the surface shape requirements of the optical system for the plane mirror. Background technique [0002] At present, in the precision optical system, there are two known flat mirror placement devices: one is V-shaped support placement, and the other is to place the flat mirror on a device with a thin steel strip, and then place the device on the air floating platform. superior. The first method is simple and convenient, but because the V-shaped support and the plane mirror are in line contact, it will cause a large deformation of the plane mirror, which is likely to fail to meet the surface shape requirements; the second method can achieve higher shock absorption and high precision Adjustment requirements, but the whole set o...
