摘要 |
<p>The invention relates to an optical sensor device (1) comprising a substrate (2) on which at least one light source (4), such as an LED, is arranged, from which at least one optical waveguide (7) leads to at least one receiver (5), such as a photodiode, to which an evaluating unit (6) is connected, wherein the optical waveguide (7) is accessible in a sensor region (8) for a change of the evanescent field of the optical waveguide present there; an optical layer (3) made of material that can be photopolymerized is applied to the substrate (2), wherein the optical waveguide (7) is structured by an exposure process in said optical layer, wherein the optical waveguide (7) is led to the surface (9) of the optical layer (3) in the sensor region (8).</p> |
