Abstract
The crystal contains a lense and three supporting elements, one of which is filled in the shape of a sector and is located diametrically to the other two. The two supporting elements are formed as bent opposite arches, ending with a concave curve, while a sector of the third supporting element has a recess, turned to the side of the optical part of the lense. All supporting elements are located at the lense's surface.
