Coated component

摘要

The invention concerns an infrared sensor, in particular an optical finger navigation module, with a component used as a cover glass for the sensor, the component comprising a sensor region and a transparent region, the transparent region comprising a thin layer system which is at least partially transparent for visible light and comprises at least one layer, and the at least one layer being a metal layer, a semiconductor layer and/or a combination of a plurality of metals and/or a plurality of semiconductors, or comprising a combination of at least one metal and at least one semiconductor, characterized in that both the sensor region and the transparent region are covered with a UV-hardening hardened lacquer layer.
