The bore comprises a bedplate (1), attachment device (3) for the lens (5), rotation device (9) for the lens (5) according to a first axis (7) (first degree of freedom), and a support column (11) with a head (15), wherein the attachment device (3) and the support column (11) can be moved between each other (second degree of freedom). The support column (11) has a first end linked to the bedplate (1) being capable of rotating about a second end (third degree of freedom) and the head (15) is linked to the column (11) by translation structure (fourth degree of freedom). The apparatus only has these four degrees of freedom in order to fix the relative position between the head (15) and the lens (5).
