Optical module with an anti-collision device for module components

The present invention relates to an optical module having a first and a second component (108, 109), a support structure (112), and an anti-collision device (114). The first component (108) is supported by the support structure (112) and to the second component (109) with a gap spaced. The support structure (112) defines a relative path of movement, on which the first and second components (108, 109) move relative to each other under the influence of a failure, wherein it during inactivity of the anti-collision device (114) to a collision between the collision portions (108.1, 109.1) the first and second component (108.1, 109) comes. The anti-collision device (114) includes a first anti-collision unit (114.1) at the first component (108) that generates a first field and a second anti-collision unit to the second component (109) associated with the first anti-collision unit (114.1) and a second field generated. The first and second field generating with increasing proximity of the first and second components (108, 109) an increasing counteracting approaching drag on the first component (108). The first and / or second anti-collision unit (114.1, 114.2) comprises a plurality of sub-fields generating anti-collision elements, which are associated with each other such that the overlapping subarrays generate a field with a field line density with increasing distance from the anti-collision unit (114.1, 114.2) along the relative path of movement falls more than a field line density of one of the sub-fields.
