  • Pyrotechnic priming device having a microlens set by a shape memory material and pyrotechnic chain utilizing said device
    Patent number: 5052300
    Abstract: A miniature photopyrotechnic priming device having a hollow body (18) for receiving a pytotechnic substance (24). A rigid index gradient microlens (30) is mounted in the hollow body for focusing a high energy beam having a given wavelength onto the pyrotechnic substance. A shape memory alloy or metal ferrule (32) is located in the hollow body (18) which has a smaller internal diameter at ambient temperature than the diameter of the microlens. A connector (34) fixed to the body (18) secures the microlens-ferrule assembly and an optical fiber (12) carrying the laser beam.
