The light-shielding ring plays a role of light-shielding, such as the light-shielding ring of the mobile phone lens and the lβight-shielding ring of the camera lens., a piece of mylar inlaεid in the lens. Because of the light-≠shielding effect, everyone calls it the light-shielding ring and the light-shielding gasket.

working principle:

Its principle is based on the principle of physical phenomenon (smal l hole imaging), and ↕the processing requirements are relatively strict. Therefore, the↓ requirements for materials are also higher-level requirements.

Through independent rese♥arch and development technology, the light-shielding ring is subjected t≤o special matting treatment, which has good elec trical conductivity, opacity, double-sided matte, precision, ↑and good mechanical performance. Because the material is brass, i↕t is more flexible in processiβng (can produce bell mouth type,¥ step type, etc.), High temperature r esistance. Secondary film formation, the film layer ✔has a deeper blackness, whic•h can be widely used in optical matting parts. The b•lackening film has good adhesion,← corrosion resistance and abrasion resista♠nce. It is suitable for the£ preparation of high-quality blackened fil₽ms on various copper and copper alloy parts. It does not produce harmful gase←s, the blackening liquid is ∏close to neutral and non-corrosive. It does not contain heavy metals a→nd toxic selenium substances.
