Adjustment device for lens is provided with axially movable optical member connected to main frame by sliding frame and incorporates linear drive producing linear movement in first axial direction.

摘要

The adjustment device is for a lens with an axially movable optical member (6) and is connected via a sliding frame (4) with a main frame (1). A first linear drive (3,7) produces a linear movement in a first axial direction and is connected with a drive member (2). The first linear drive is connected with a second linear drive (12,13) by positioning members (5). The second linear drive produces a linear movement along the optical axis (14) and is connected with the sliding frame (4).
