This invention relates to a sled-guide-assembly, in particular for an
optical attenuating device, comprising a straight guidance and a sled,
which is movable within the guidance, wherein
the guidance has an inner contour, comprising two guide rails, extending
parallel to each other,
the inner contour comprises a receiving space between the guide rails,
the sled comprises an outer contour arranged in the receiving space, and
supports an object, in particular an optical attenuating element, outside
of the receiving space,
the outer contour comprises first edges and second edges,
the first edges rest against the guide rails at a first side, which is
turned to the object, and overlap this first side transversally to the
longitudinal direction of the guide rails,
the second edges rest against the guide rails at a second side, which is
turn away from the object, and overlap this second side transversally to
the longitudinal direction of the guide rails,
the second edges are flexible and abut with tension against the guide
rails.
