　　The working principle of the s≈hading ring:

　　Its principle is based on the principle of physical✔ phenomena (small hole imaging), and the processing☆ requirements are relatively stri ct. Therefore, the requirements for material★s are also higher-level r™equirements.

　　The company is the only domestic suppli®er of copper light-shielding rings for ultra-thin precision micro-optical lense✔s with independent knowledge rights. The material∞ of the company is brass; the light-shielding ri"ng is specially optically dyed¥ and matted through independent research and development technology, and it₩ has good electrical conductivi™ty and double-sided. Frosted, precise size, thickness up to 0.05-0.1<0, no light transmiss↓ion, stable mechanicaπl performance, high temperature resistance, has obtained nationγal invention patents, suitable for more than 3 million design ca♠meras, lenses, vehicles, etc., lens upgrade essentials, it is ♠PET The ideal renewal pro✘duct of the product is the best choice for your product upgrade.
