  • Method of fabricating structures, starting from material rods
    Patent number: 10260152
    Abstract: A method, and corresponding apparatus, of fabricating a structure by chemical wet etching starting from a material rod of millimetric or sub-millemetric size, the method comprising: dipping an end portion (170) of the material rod (128,129) into a vessel (105) containing an etchant liquid (110) and a protective overlayer (175) floating on top of the etchant liquid, imparting a relative rotational movement of the etchant liquid with respect to the end portion (170) of the material rod immersed therein, wherein said imparting a relative rotational movement comprises imparting to the etchant liquid a rotational movement component with respect to a static reference system.

  • Method and apparatus for the immobilization of vitreous supports at the ends of plastic or glass optical fibers for the construction of fiber-optic chemical sensor
    Patent number: 5530779
    Abstract: A description is given of a method for the construction of a fiber-optic sensor in which a chromophore is fixed on a support and said support is linked to at least one optical fiber for the transmission and reception of a light signal. According to the invention, the end of the optical fiber (F) is heated and brought to a softening temperature, and the support (S) is immobilized on the optical fiber (F) by partially incorporating it in the softened portion of the optical fiber and subsequently cooling and solidifying the optical fiber.
