1. A test system for optically checking an electrical line, the test system comprising:
a test area for arranging the electrical line;
a plurality of prisms surrounding the test area;
a camera directed at the prisms, the camera configured to optically detect the electrical line arranged in the test area through the prisms from different sides;
a shielding mechanism having a curved inner contour which encloses the test area and the prisms at least in a radial direction;
an air duct, at least indirectly connected to a nozzle directed towards the test area and designed to have at least some prism surfaces facing the test region with a cleaning air flow and thereby entrain dirt particles present on the at least some prism surfaces; and
further air ducts arranged to open into an area of the inner contour of the shielding mechanism and configured to convey the inner contour of the shielding mechanism in two opposite circumferential directions with respective entraining air flows which direct the cleaning air flow together with the entrained dirt particles into an air diffuser or outlet in a lower region of the inner contour of the shielding mechanism.
