Abstract (en)
[origin: EP0368299A1] In an apparatus for checking the relative position of at least two optical axes, in order to guarantee the axial parallelism of the incoming and outgoing light beams independently of bends occurring in the carrier tubes for the optical deflection systems, according to the invention the deflection optics of each deflection system is composed of two or more optical deflection elements (5) of inherently stable position. At the same time, adjacent deflection elements are so arranged offset relative to one another that their beam entry and exit regions overlap one another. <IMAGE>
