A type of modern high explosive lenses without wave shaper. The colored areas are the fast explosive, while the white areas are the slow explosives.In an implosion-type nuclear weapon, polygonal lenses are arranged around the spherical core of the bomb. Thirty-two "points" are shown. Other designs use as many as 96 or as few as two such points.
An explosive lens—as used, for example, in nuclear weapons—is a highly specialized shaped charge. In general, it is a device composed of several explosive charges. These charges are arranged and formed with the intent to control the shape of the detonation wave passing through them. The explosive lens is conceptually similar to an optical lens, which focuses light waves. The charges that make up the explosive lens are chosen to have different rates of detonation. In order to convert a spherically expanding wavefront into a spherically converging one using only a single boundary between the constituent explosives, the boundary shape must be a paraboloid; similarly, to convert a spherically diverging front into a flat one, the boundary shape must be a hyperboloid, and so on. Several boundaries can be used to reduce aberrations (deviations from intended shape) of the final wavefront.
