Title: Optical module with integrated source of light

Abstract: An optical module includes a lens arrangement which is used to project electromagnetic radiation to a semiconductor element and a light source disposed in the surrounding area of the radiation inlet area of the lens arrangement. The lens arrangement and the light source are provided with a covering which is permeable to electromagnetic radiation. The covering is provided with a radiation barrier that blocks the radiation which is emitted by the light source and prevents a direct injection of radiation which is emitted by the light source into the lens arrangement.
