　　The shading ring plays a role in shading, for example§, the shading ring of the mobile phone lens and t∑he shading ring of the camera lens. It is ↑a piece of Mylar sheetφ that is stamped and for←med with SOMA shading material and embedded  in the lens. Because of the shad‌ing function, everyone calls it Shading rπing, shading gasket. Its principle is based on the principle of phy♠sical phenomena (small hole imaging), and th∑e processing requirements• are relatively strict. Therefore, the requirements for mate∞rials are also higher-level requirements, and the Japa★nese SOMA shading materials are b®asically used in the market. .It is a double matte black ΩPET.

　　With the development of mobile phone∞ camera technology, the requirements for mobile phone lenses are gettin↕g higher and higher. The existing mobile pho'ne lenses are generally composed of multiple lenses. In oαrder to block excess lφight, a light-shielding ring is installed between t he lenses.

　　The aperture is one↕ of the indispensable parts of an optic×al lens, and the existing connection me✔thod of the aperture and the lens is generally γto directly fix the ape∞rture on the lens body. At present, there are two commonly used fixi÷ng methods, one is to use screws to pass through the mounting holes; the oth♦er is to use screws to press on the side. The screw holes for these two fixing methods☆ are on the lens body; the fixin g method passing through the mounting hol©e causes the lens body to have a strange appearance and make¥s the lens body larger in size; while the screw side pre♣ssing fixing method is easy to damage the iris . In addition, the product cost  of these two fixing methods is relativelγy high.
