PHOTOPYROTECHNICAL DETONATION DEVICE AND PHOTOPYROTECHNICAL CHAIN USING THIS DEVICE

摘要

17 A photopyrotechnical detonating device and a photopyrotechnical chain using this device are disclosed. A pyrotechnical charge, which can be actuated by a laser beam, is placed in a solid body. The beam is conveyed by an optical fiber which penetrates a connector mounted on the body. The beam, which is divergent when it leaves the fiber, is made parallel by a first lens. A second lens, mounted on the body, makes the beam converge and works with a transparent barrier to focus the beam on a given point. Tight-sealing means are provided between the transparent barrier and the body of the device, thus ensuring the containment of the charge.
