Device in imaging optical system for moving film camera has stationary plate with image field marking parallel to the plane of moving plate and at minimal distance from moving plate

摘要

The device has at least one movable, transparent setting plate (4a-4c) (matt plate, fiber plate or similar) with a drive device for moving it in its plane. A stationary plate (5) with an image field marking (81,82) is arranged parallel to the plane of the movable plate and at a minimal distance from the movable plate.
