     Composed of several cambered blades, the OMDC series cage system diaphragms have a structure similar to the diaphragms at the rear of camera lens. As one-piece variable diaphragms, this series is designed for 16 mm, 30 mm, or 60 mm cage systems. It delivers appropriate damping between blades without blockage and loosening by virtue of its elaborate design and our favorable assembly processes. Using variable diaphragms as space spatial filtering makes it possible to continuously adjust the center hole size. This greatest advantage facilitates the passage of some frequency components and the blockage of other frequency components on the spectrum range, thus changing the frequency components of the image surface.
