Device for the spatially resolved introduction of an intensity pattern of electromagnetic radiation into a photosensitive substance

摘要

Device for the spatially resolved introduction of an intensity pattern (5) of electromagnetic radiation into a photosensitive substance (2) with properties which can be changed by photon radiation, comprising a photosensitive substance (2) whose properties can be changed by photon irradiation between a first, liquid and at least one second state, and a radiation source and an optical imaging system (3) for introducing an electromagnetic radiation (4) originating from the radiation source into the photosensitive substance (2) and for mapping the electromagnetic radiation (4) in the photosensitive substance (2) to predetermined spatial coordinates (5 ) to produce at these location coordinates or in these surrounding areas a change in the substance properties, characterized in that the optical imaging system (3) comprises a lens (3) which is designed as an immersion objective, the device ausgestal tet is that a surface (6) of an objective lens of the objective (3), through which the electromagnetic radiation (4) exits therefrom, for introducing the electromagnetic radiation (4) is immersed in the photosensitive substance (2) in this.
