Claims (10)

  1. Procédé de blocage d'une lentille optique (100) sur une unité de maintien thermoconductrice (200) comprenant une partie inférieure (220, 230) à insérer et à fixer dans un outil d'usinage de lentille et une partie supérieure (250) comprenant une surface d'assemblage supérieure (210) comprenant les étapes de :
    a) la fourniture d'une première couche se composant d'un ruban adhésif (330) sur la surface d'assemblage supérieure (210) de l'unité de maintien ;
    et caractérisé en ce qu'il comprend en outre les étapes de :
    b) la fourniture d'une deuxième couche se composant d'une couche (310) comprenant un matériau thermoplastique agencé sur ledit ruban adhésif (330) ;
    c) la fourniture à la lentille optique (100) d'une troisième couche se composant d'un ruban adhésif (320) agencé sur la surface inférieure (120) de ladite lentille optique ;
    d) le placement de la lentille optique (100) avec la troisième couche (320) sur la deuxième couche (310) se composant de la couche comprenant le matériau thermoplastique lorsque le matériau thermoplastique est assoupli ou fondu.
  2. Dispositif de blocage de lentille optique comprenant :
    - une unité de maintien thermoconductrice (200) comprenant une partie inférieure (220, 230) à insérer et à fixer dans un outil d'usinage de lentille et une partie supérieure (250) comprenant une surface d'assemblage supérieure (210) ;
    - une première couche se composant d'un ruban adhésif (330) placé sur la surface d'assemblage supérieure (210) de l'unité de maintien ;
    et caractérisé en ce qu'il comprend en outre :
    - une deuxième couche se composant d'une couche (310) comprenant un matériau thermoplastique empilé sur la première couche (330) ;
    - une troisième couche se composant d'un ruban adhésif (320) empilé sur la deuxième couche (310).
  3. Dispositif de blocage de lentille optique selon la revendication précédente, dans lequel la surface d'assemblage supérieure (210) de l'unité de maintien est une surface sphérique.
  4. Dispositif de blocage de lentille optique selon la revendication 2 ou 3, dans lequel le point de fusion ou d'assouplissement du matériau thermoplastique de la deuxième couche (310) est entre 45°C et 75°C.
  5. Dispositif de blocage de lentille optique selon l'une quelconque des revendications 2 à 4, dans lequel les rubans adhésifs (320, 330) ont une surface adhésive sensible à la pression (322, 334) agencée pour entrer en contact avec une surface inférieure (120) d'une lentille optique ou la surface d'assemblage supérieure (210) de l'unité de maintien et une surface de promotion d'adhésion non collante (324, 332) agencée pour entrer en contact avec les surfaces (312, 314) de la deuxième couche (310).
  6. Dispositif de blocage de lentille optique selon l'une quelconque des revendications 2 à 5, dans lequel l'épaisseur de la deuxième couche (310) est entre 0,5 mm et 2 mm, par exemple inférieure ou égale à 1 mm.
