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 shown embodiment, a microcrystalline plane 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 through a suspension block 4 and a half-threaded bolt 5 of M14, and the lateral screw adjustment is adjusted. Rod 6 withstands both sides of plane mirror 1, loosen adjustment screw rod 7-1 and tension adjustment screw rod 7-2 in combination to make tension steel belt 7-3 pull plane mirror 1, and adjust back thread adjustment rod 8 to withstand plane mirror 1, Adjust the bottom threaded adjustment rod 9 to realize the adjustment of the plane mirror 1 up and down and pitch direction.

The invention discloses a shock-absorbing adjustment mechanism for a plane mirror. The plane mirror is suspended on the main structure by a thin steel belt through half-threaded bolts. The side thread adjustment rod of the plane mirror, the back adjustment mechanism, the back thread adjustment rod, and the bottom thread adjustment rod jointly realize the shock absorption and high-precision adjustment function of the plane mirror. The advantage of the shock-absorbing adjustment mechanism is that the plane mirror can quickly enter a stable state through the high-precision adjustment mechanism under the condition that the plane mirror is only slightly deformed.
Description
technical field [0001] The invention relates to a plane mirror adjustment device, in particular to 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 satisfies 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 devices for placing the plane mirror: one is to place the plane mirror on a V-shaped support, and the other is to place the plane mirror on a device with a thin steel belt, and then place the device on an air-floating platform superior. The first method is simple and convenient, but because the V-shaped support is in line contact with the plane mirror, it will cause a large deformation of the plane mirror, which may not meet the surface shape requirements; the second method can achieve higher shock absorption and high precision Adjustment requirements...
