METHOD FOR MANUFACTURING OF X-RAY REFRACTORY LENS WITH MINIMISED ABSORPTION, HAVING ROTATION PROFILE Russian patent published in 2009 - IPC G21K1/06 

FIELD: technological processes.

SUBSTANCE: application: for manufacturing of X-ray refractory lenses. Substance: consists in the fact that lens matrix is manufactured from material capable of photopolymerisation, formation of one or several lenses with required focus distance, talking into account number and geometric characteristics of these lenses, characteristics of these lenses material and holder material, and also dynamic mode, in which lens matrix is generated, besides, produced matrix is used to form one or several bases for lenses, for this purpose material is introduced, which has no adhesion to matrix material, in matrix base material is transferred into solid phase, produced base is separated from matrix, is placed in bath with liquid photopolymer on piston with precision travel of linear displacement, then photopolymerisation is carried out through set of masks with annular clearances and radial slots, where internal radius of annular clearance is identified as , and external radius - as , where m is even number, base is shifted by value equal to even number of phase shift lengths L=mλ/δ, operations of exposure through the subsequent masks and shift are repeated until specified number of segments is obtained, lens is separated from base, and lens is installed in holder.

EFFECT: improved focusing properties of lenses with rotation profiles.
