The invention is concerned with the problem of providing an automatic inspection device, with which it is possible to determine, with little effort and without contact, whether packages, particularly sealed blister packages consisting of a blister container and a cover film, are free of defects. This problem is solved by the use of at least two light sources, which are arranged at a certain distance from one another and each emit a light bundle at a predetermined wavelength range, whereby the emission maxima of the two light sources are offset in relation to one another. The light sources are arranged such that the packages are vertically illuminated. The light reflected by the packages is recorded by a CCD camera and the digital images are stored in a computer, so that they are available in a computer-supported image-processing and documentation system.
