Abstract

The invention relates to an apparatus for controlling the quality of transparent objects, comprising at least one light source being adapted to illuminate the object, and at least one image capturing device, by means of which at least one image of the object can be detected, wherein the apparatus comprises further at least one reflector, wherein the reflector and the image capturing device define a beam path, wherein the reflector, the image capturing device, and the light source are arranged such that the object can be arranged between the reflector, on the one hand, and the image capturing device and the light source, on the other hand, such that a single sheet of material is located in the beam path. Furthermore, the invention relates to a corresponding method for controlling the quality of transparent objects.
