OPTICAL IMAGING ELEMENT AND MODULE FOR AN OPTICAL SEMICONDUCTOR COMPONENT, METHOD FOR PROCESSING AN OPTICAL IMAGING ELEMENT AND IMAGE CAPTURE APPARATUS

摘要

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.
