Abstract
An apparatus for inspecting empty containers in order to detect dirt therein is disclosed. A radiation source generates exciting radiation, and the exciting radiation is directed onto the inner wall of a container and excites dirt to be detected in such a way that the dirt emits luminescent radiation. At least one device detects the luminescent radiation emitted by the dirt, and another device analyzes the detected luminescent radiation. Also disclosed is a corresponding method for inspecting empty containers in order to detect dirt therein.

Apparatus for inspecting empty containers for contaminants, comprising
- a pulsed radiation source for generating an exciting radiation, wherein the pulsed radiation source is configured such that:
- the exciting radiation is directed on to the inner wall of a container having an internal space,
- the exciting radiation illuminates all of the internal space;
- and
- the exciting radiation excites contaminants to be detected in such a way that they emit luminescent radiation,
- at least one device for detecting the luminescent radiation emitted by the contaminants, and
- a device for analysing the detected luminescent radiation.
Method for inspecting empty containers for contaminants, comprising the steps:
- irradiating the inner walls of a container with an exciting radiation from a pulsed radiation source, wherein
- the container has an internal space and the exciting radiation illuminates all of the internal space, and
- the exciting radiation excites contaminants to be detected in such a way that they emit luminescent radiation;
- detecting the luminescent radiation emitted by the contaminants using a detection device;
- and
- analysing the detected luminescent radiation in an analysing device.
