The present invention relates to a finger tester for the testing of non-componented printed circuit boards using at least two test fingers ( 1 ), each of which has a test probe ( 2 ), and wherein there is provided above each test probe ( 2 ) a detection device ( 20 ) for optical detection of the position of at least one contact tip of the test probe ( 2 ). The detection devices ( 20 ) of the two or more test fingers ( 1 ) are arranged in different vertically spaced planes, so that at least areas of the detection devices ( 20 ) located above the test finger ( 1 ) may be positioned above one another, aligned vertically without contact.
