Abstract
An imaging device is provided with an image sensor element (1) for electromagnetic radiation (11) with a covering body (2) which is transparent and to the radiation (11) through which the radiation (11) can reach the sensor element (1). The imaging device is characterized in that a transparent electrically-conducting layer (3) is provided on the covering body (2) and is provided with two connection electrodes (4, 5) for heating of the covering body (2) with an electric power supplied through the electrodes (4, 5) and dissipated in the transparent layer (3). It is possible with such an imaging device to prevent condensation of a water film on the covering body (2) under conditions where the temperature of the covering body (2) lies below the dew point of the surroundings.
