Abstract
An apparatus () serves for linear illumination of a moving product web (), the apparatus () having at least one light source () emitting light. In order to achieve high luminance in a linear subregion of the product web (), at least a portion of the light emitted by the light source () is reflected towards the product web () by at least one tubular reflector (). The tubular reflector () in this case has at least one light exit slit () which is assigned to the product web (). Moreover, the tubular reflector has at least one observation slit () which lies opposite the light exit slit (). The illuminated product web () can be observed through this observation slit () by means of a line camera ().
