The explosive lenses around nuclear charges are also designed to be highly insensitive, to minimize the risk of accidental detonation.

The pusher is located between the explosive lens and the tamper.

A more efficient two-point implosion system uses two high explosive lenses and a hollow pit.

This is sufficiently precise for very low tolerance applications such as nuclear weapon explosive lenses.

It was also used for the explosive lenses in the first implosion-type nuclear weapons developed by the United States.

One of the latest tools used at the research center is a device designed for nuclear weapons called an explosive plane-wave lens.

The explosive lens underneath seemed to shrug and then slide into place.

The explosive lenses were designed primarily using this series of tests.

There, he worked on the hydrodynamic calculations to predict the behavior of the explosive lenses that were needed by an implosion-type weapon.

The mechanical group dealt with the exploding-bridgewire detonators and the explosive lenses.
