What are the characteristics★ of the shading ring
The shading ring plays a role of shading, such as the shεading ring of the mobile phone lens and the lens shading ring of th§e camera lens. It is a piece of Mylar sheet t∑hat is stamped with SOMA shading material and embedded in the lens. Because o∞f the shading function, everyone calls it Shading ring, shading g¥asket.
What is the principle function of the shading ring?
The shading ring plays a role of shading<, such as the shading ring of the mobile phone lens and the∑ lens shading ring of the camera lens. It i♠s a piece of Mylar sheet that is stamped with SOMA shading material and em×bedded in the lens. Because of the shading fu•nction, everyone calls it Shading ring, shading gasket.
The shading Mylar sheet is die-cut (DIECUT") and punched into sheets according to the requirements of the drawings or spe₽cified.
A brief introduction to the application of Mylar tablets
The film is biaxially stretched by heating with t≥he aid of a catalyst, transestβerification and vacuum polycondensation.
Fixing the visor ring of mobile phone lens
The shading ring on the traditional lens is controlled by the aperture leaf₹, and the reduction of the aperture l±eaf can reduce the amount of light entering the photosensitive element, therebλy controlling the depth of field and image quality of the pictur¶e.
The role of the shading ring on the phone± lens
The principle of the light-shielding ring is based on the principle of physica"l phenomena (small hole imaging), and the ₩processing requirements are ±relatively strict. Therefore,↓ the requirements for materials also have higher-level requiremen£ts.
