Abstract
A 2D barcode scanner () comprises a housing () having a reading window () and a digital camera () arranged in the housing () for detecting the area of the reading window () either directly or via a deflecting mirror arrangement (). At least one external light source () is provided for illuminating an area in front of the reading window () in the housing (), at the side of the reading window () that is facing away from the digital camera (). At least one external light source () is provided with an optical adapter () by which the light therefrom is distributed, such that the reflection paths are not illuminated at the inside of the reading window () back into the camera (), or are illuminated with a very low intensity. This avoids or significantly reduces the intensity of the light reflections that arise on the inside of the reading window () and are superimposed on the barcode that is to be read as very bright spots in the image of the digital camera ().
