X-RAY ZOOM BASED ON REFRACTIVE LENSES Russian patent published in 2023 - IPC G03B19/04 

FIELD: optical systems.

SUBSTANCE: invention is designed for instrumental focusing, step change in the focal length of the X-ray optical system, control of parameters of the flow of X-rays (XR) and synchrotron radiation (SR) in SR channels. The essence of the invention lies in the fact that the X-ray zoom lens based on refractive lenses includes transmission units that transmit motion from the motors to the actuating elements - lamellas, which are flat parts in form of plates, each lamella contains an element without clearance fixation of the refractive lens in the mandrel, the central element without movable clearance fit on the shaft and the tail element, these lamellas form a system of lamellas, made with the possibility of rocking movements relative to the lamella shaft installed in the central hole of the lamellas, thereby moving the refractive lenses in the mandrels, as well as with the possibility of independent movement relative to each other by means of a lamella driver making linear movement in a cylindrical coordinate system, and being engaged with the tail part of a given number of lamellas pivotally mounted on a fixed lamella shaft, carrying out their angular movement, which ensures the input of refractive lenses into the X-ray beam and the output from it.

EFFECT: providing the possibility of reducing the dimensions and weight, providing the ability to carry out precise positioning of refractive X-ray lenses, as well as a stepwise change in the focal length of the X-ray optical system.
