Process and apparatus for the manufacture of an optical component
An optical component is prepd. by (a) preparing a transparent substrate of high refractive index n1, (b) depositing on the substrate a photo-polymerisable substance of refractive index n2; and illuminating the photo-polymerisable substance with a light beam, to reveal the imprint of the light beam....

| description | An optical component is prepd. by (a) preparing a transparent substrate of high refractive index n1, (b) depositing on the substrate a photo-polymerisable substance of refractive index n2; and illuminating the photo-polymerisable substance with a light beam, to reveal the imprint of the light beam. The light beam illuminates the photopolymerisable substance through a substrate at an angle of incidence, (i) such that n1/n2 sine (i) is greater than 1 before and after the polymerisation, producing an evanescent zone in the neighbourhood of the interface between these two media.
La présente invention concerne un procédé et un dispositif de fabrication d'un composant optique. On dépose sur un substrat d'indice n1, une substance photopolymérisable d'indice n2. On éclaire la substance photopolymérisable à l'aide d'un faisceau lumineux, au travers du substrat sous un angle d'incidence i, tel que ((n1) / (n2)) sin i > 1, de façon à produire une zone d'évanescence au voisinage de l'interface entre les deux milieux. On traite la substance photopolymérisable de façon à révéler l'empreinte du faisceau lumineux. On obtient ainsi des composants définis avec une grande précision. |
