The openness of following case has been allowed by our clients with exception of key parameters, which is only 90% of complete design process. I. Application For camera lens II. Requirements Shell maximum axial size: less than 4 mm Shell maximum radial size: less than 40 mm Maximum clear aperture (diameter) : more than 22.4 mm Minimum clear aperture (diameter) : less than 2.8 mm Aperture quantity: ten pieces III. Features This aperture is used for camera lens, and its axial don't need to be locked, and slice thickness is only 0.05 mm (and overlapping), so it is easy to fufill requirements on axial size . The difficulty of design is to determine the shape of the aperture thus to meet other requirements.
