Problems solved by technology
But when the radius of curvature is less than 60mm, the contact area between the bottom of the lens and the support surface becomes smaller, and the overall quality of the lens becomes lighter, making it difficult to stand freely
Even if it stands successfully, during the test, if there is a slight external shock or wind, the lens may fall down, thus interrupting the test
At the same time, due to the ultra-thin lens, there is a high risk of damage after being dumped. Considering the production cycle of the lens, if the lens is damaged, it will cause greater cost and time loss

Embodiment Construction
[0026] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. This embodiment is carried out on the premise of the technical solution of the present invention, and detailed implementation and specific operation process are given, but the protection scope of the present invention is not limited to the following embodiments.
[0027] The invention realizes a fixing device of a large-curvature ultra-thin cylindrical lens for laser scanning test, which can be applied to a laser scanning system. like figure 1 As mentioned above, the laser scanning system is mainly composed of three parts: the laser light source S1, the control platform group S2 for adjusting the position of the lens, and the linear displacement stage group S3. The test principle is: the beam emitted by the laser is incident on S3 after passing through two rotating mirrors, and the beam is deflected upward by 90° through a pentaprism to a beam...

Abstract
The present invention relates to a fixed device of a large-curvature ultrathin cylindrical surface lens for laser scanning test. The device comprises: a pedestal (7), wherein the pedestal (7) is provided with a bottom groove (5) configured to put a large-curvature ultrathin cylindrical surface lens; an adjustable U-shaped front bumper vertically arranged on the pedestal (7), wherein the adjustableU-shaped front bumper is provided with a dual-face adhesive tape bonding position (6) configured to fix the large-curvature ultrathin cylindrical surface lens; and an E-type rear bumper (4) vertically arranged on the pedestal (7) and arranged in parallel with the adjustable U-shaped front bumper. Compared to the prior art, the fixed device of a large-curvature ultrathin cylindrical surface lens overcomes the defect that a large-curvature ultrathin cylindrical surface lens cannot freely stand, can perform effective fixed arrangement for a 60-degree sector cylinder surface lens having curvatureradius of not larger than 60mm, has advantages of avoiding an influence of an external force on the lens test and improving the lens surface shape precision, can have a protection effect on the ultrathin lens and is not easy to damage when test accidents are generated.
Description
technical field [0001] The invention relates to the detection field of X-ray reflectors, in particular to a fixing device for large-curvature ultra-thin cylindrical mirrors for laser scanning testing. Background technique [0002] X-ray astronomy is a branch of astronomy that studies the X-ray radiation of celestial bodies. The photon energy range of the observed object is between 0.1 and 100keV. Usually, X-rays from 0.1 to 10keV are called soft X-rays, and X-rays from 10 to 100keV are called hard X-rays. X-ray telescope is an important observation instrument in X-ray astronomy. Due to the nature of X-ray itself, the phenomenon of total reflection will only occur at grazing incidence. According to this phenomenon, the currently widely used X-ray imaging telescope is the Wolter-I grazing incidence imaging telescope named after him proposed by the German scientist Wolter in 1952. However, in the case of grazing incidence, the higher the energy of X-rays, the smaller the criti...
