Although the light-shielding spacer and Mylar lens are very small parts in the CMOS lens, they ≤play a very important role in determining the image clarity, aperture βsize, optical focus and many ot↑her optical parameters. Many factories consider it to be inconspicuou>s. Small things, random selection of suppliers, even without serious assess←ment of the supplier’s qual↕ity system, mass production capacity, and ™technical strength. As a result, t↑he lens FLARE (light and shado↓w), black spots, offset and other quality abnormalities occur from time to t>ime, and they are scrapped. It's not just a ∏small piece of light-shielding washer, but the entire f∏inished lens. It's really a smallφ loss that is not worth the loss. At present, among the len₩ses of IPHONE, SAMSUMG, and HUAWEI, their high-definition ÷lenses are made of Japanese original high-end shading materia♠ls such as KIMOTO or blackened matt stainless steel. At the same time, in ∑order to eliminate mechanical stray light such as FLARE, th‌e inner wall of the inner hole must be chamfered and merged. H♥ole frosting and matting treatment€. In addition, in order to cooperate δwith lens research and deve™lopment, special processing is also necessary for the ultra-precisio>n machining of the inner hole and R angle control>. Especially for the problem of BURR, which has th→e most quality problems, it must be used " Fullεy automatic enlargement of 100X photographic monitoring and idΩentification system" to ensure the outflow of defective products "0".
