　　The shading ring is based o n the principle of physical phenomenon (small hole iεmaging), and the processi↓ng requirements are relatively strict.

　　Therefore, the requirements for materials εalso have a higher level of demand.± The Japanese SOMA sha¶ding material is basically used in the market.£ It is a double matt black∏ PET.

　　The shading ring plays a role of shading, ☆such as the shading ring of t☆he mobile phone lens and the lens shading ring of the camera lens. It is a pieεce of Mylar sheet that is s₹tamped with SOMA shading material and embedded in the lens. ←Because of the shading function, everyone calls it Shading$ ring, shading gasket. It✘s principle is based on βthe principle of physical phenomenon (small hole imaging), and the processin'g requirements are relatively strict.

　　Digital camera or ♣mobile phone lens, surve≥illance lens, car lens, etc. SOMA shading ring, shading film, SOMA shad∏ing Mylar film, tolerance is plus or minαus 0.01. The company specializes in manufacturing high-precision metal ♠stamping molds and precision stamping products for metal and non-metal sh✘eets. The outer dimension tolerance can be guaran↓teed to be within ±0.005MM, and the concentr≥icity is guaranteed to be within ±0.01MM, which has the f×unction of ultra-thin processing.‍
