FOTOPYROTEKNISK TENNINNRETNING OMFATTENDE EN MIKROLINSE INNFATTET I ET HUKOMMELSESMATERIALE OG PYROTEKNISK KJEDE SOM BENYTTER INNRETNINGEN.

摘要

The igniter device according to the invention is a miniature device comprising a hollow body 18 intended to receive a pyrotechnic substance 24, a microlens which is rigid with an index gradient 30 mounted in the hollow body in order to focus an energy beam of given wavelength, on the pyrotechnic substance, a ferrule made of a material with form memory 32 housed in the body 18 ensuring the locking of the microlens in the body of the device, the internal diameter, at room temperature, the ferrule is less than the diameter of the microlens, a connector 34 fixed on the body 18 ensuring the holding of the microlens - ferrule and that of the optical fiber 12 carrying the laser beam.
