Problems solved by technology

However, due to the large spatial distance of the focusing optical system, spatial stability is very important; in addition, to meet the needs of micro-nano spatial resolution, the grazing incidence mirror needs to be able to adjust the focus spot size to adapt to different samples and methods, and to achieve different scientific experiment purposes. Traditional fixed surface mirrors are no longer adequate for this application

Embodiment 2

[0047] This embodiment provides a dynamically stabilized micron focusing system, which includes a plurality of the dynamic bending adjustment devices described in the first embodiment, and the multiple dynamic bending adjustment devices are combined together to form a Kirkpatrick-Baez optical focusing system, Montel type optical focusing system or Wolter type focusing optical system.

[0048] like image 3 As shown, that is, a Kirkpatrick-Baez focusing optical system composed of two dynamic press-bending adjusting devices, wherein the two dynamic press-bending adjusting devices are arranged in front of each other and are orthogonal to each other. During use, the grazing incident light in the direction of the arrow is reflected and focused into a line by the grazing incidence mirror of the first dynamic press-bend adjustment device, and then reflected by the grazing-incidence mirror of the second dynamic press-bend adjustment device for a second time. The reflection is focused...

Abstract

The invention relates to a dynamic bending adjustment device and a dynamic stable micro-focusing system, comprising a compliance mechanism, which is supported on two mounting seats at the bottom thereof, and an adjusting plate extending vertically upward is arranged from the upper surface of the mounting seat; two connecting pieces, which are respectively connected with the free ends of the adjustment plate and extend along the vertical surface away from the mounting seat; two micro-displacement actuators, which are respectively fixed on the two supporting frames and the side walls are respectively in contact with the two connecting pieces; the two mirror holding pieces are respectively fixed on the bottom surfaces of the two mounting bases; the grazing incidence mirrors are respectively clamped at the two ends of the mirror holding pieces and the mounting bases. between. The dynamic bending adjustment device and the dynamic stable micro-focusing system of the present invention apply a tunable bending moment to both ends of the grazing incident reflector by using a compliant mechanism, adjust the curvature radius of the reflector in real time, realize dynamic micro-focusing, and increase the focused spot size and positional stability.

Description

technical field [0001] The invention relates to synchrotron radiation beamline transmission and regulation technology, and more particularly to a dynamic bending regulation device and a dynamic stable micro-focusing system. Background technique [0002] Grazing incidence mirrors are widely used in the field of modern optical technology to deflect and focus X-ray beamlines, especially in the beamlines of synchrotron radiation light sources in large scientific installations. The commonly used mirror focusing modes include toroidal focusing and ellipsoidal focusing. and parabolic focusing, etc. However, due to the large spatial distance of the focusing optical system, spatial stability is very important; in addition, for the needs of micro-nano spatial resolution, the grazing-incidence mirror also needs to be able to adjust the focusing spot size to adapt to different samples and methods, and achieve different scientific experimental purposes. Traditional fixed surface mirrors...
