Information

  The shading ring plays a role in shading, for example, the shading ring of the mobile phone lens and the shading ring of the camera lens. It is a piece of Mylar sheet that is stamped and formed with SOMA shading material and embedded in the lens. Because of the shading function, everyone calls it Shading ring, shading gasket. Its principle is based on the principle of physical phenomena (small hole imaging), and the processing requirements are relatively strict. Therefore, the requirements for materials are also higher-level requirements, and the Japanese SOMA shading materials are basically used in the market. .It is a double matte black PET.

  With the development of mobile phone camera technology, the requirements for mobile phone lenses are getting higher and higher. The existing mobile phone lenses are generally composed of multiple lenses. In order to block excess light, a light-shielding ring is installed between the lenses.

  The aperture is one of the indispensable parts of an optical lens, and the existing connection method of the aperture and the lens is generally to directly fix the aperture on the lens body. At present, there are two commonly used fixing methods, one is to use screws to pass through the mounting holes; the other is to use screws to press on the side. The screw holes for these two fixing methods are on the lens body; the fixing method passing through the mounting hole causes the lens body to have a strange appearance and makes the lens body larger in size; while the screw side pressing fixing method is easy to damage the iris . In addition, the product cost of these two fixing methods is relatively high.
