METHOD AND MOULD TO MANUFACTURE X-RAY FOCUSING LENSES Russian patent published in 2012 - IPC G01K1/06 

FIELD: measurement equipment.

SUBSTANCE: mould is made from a metal cylinder, in the middle of which a chamber is moulded for photopolymerisation of a liquid photopolymerizing composition in the form of a regular prism. The base of the prism is an isosceles right-angled triangle. Its one face is arranged in the cylinder in parallel to the cylinder axis, two side faces forming a right angle between each other, are made from translucent glass or quartz and are detachably installed in flats arranged in the cylinder. The cylinder comprises two holes entering the polymerisation chamber for ventilation and supply of a liquid photopolymerising composition, as well as a channel along the cylinder axis. In the channel at two sides of the cylinder there are movable metal rods installed coaxially with an optical parabolic surface at the end. Parabolic surfaces are in the polymerisation chamber and face each other with tops, and the distance between them is fixed.

EFFECT: creation of a design of X-ray focusing lens permitting for location of separate X-ray lenses along the axis, and having low losses of X-ray radiation.
