  • Patent number: 8654446
    Abstract: An optical element or module is designed to be placed in front of an optical sensor of a semiconductor component. At least one optically useful part of the element or module is provided through which the image to be captured is designed to pass. A method for obtaining such an optical element or module includes forming at least one through passage between a front and rear faces of the element or module. The front and rear faces are covered with a mask. Ion doping is introduced through the passage. As a result, the element or module has a refractive index that varies starting from a wall of the through passage and into the optically useful part. An image capture apparatus includes an optical imaging module having at least one such element or module.

  • Patent number: 8354293
    Abstract: An imaging optical module is designed to be placed in front of an optical image sensor of a semiconductor component. The module includes at least one element which has a refractive index that varies between its optical axis and its periphery, over at least an annular part and/or over its central part. The element may be a tablet in front of the semiconductor sensor or a lens in front of the semiconductor sensor. The direction of variation in refractive index may be oppositely oriented with respect to the table and lens.

  • Patent number: 8253092
    Abstract: An optical die, which is intended to be placed in front of an optical sensor of a semiconductor component, has an optically useful zone having an optical axis and exhibiting a variable refractive index. Specifically the refractive index of the die is variable in an annular peripheral zone lying between a radius Ru enveloping the useful zone and a smaller radius Ro. The index varies as a function of radial distance from a lower value near the smaller radius Ro to a higher value near the radius Ru. The function of the variable refractive index lies between a maximum and minimum profile.
