Even the slightest dimensional deviations can directly lead to degraded optical performance.\u003cbr\u003eKey requirements for precision lens barrel manufacturing include:\u003cbr\u003e• Strict dimensional tolerance control\u003cbr\u003e• High-precision thread geometry\u003cbr\u003e• Extremely high concentricity\u003cbr\u003e• Consistent surface roughness\u003cbr\u003e• High-performance matte black anodization (to reduce internal reflections)\u003cbr\u003eFor most optical systems, internal reflections must be minimized. Therefore, surface treatment processes and internal wall structure design play a decisive role in the final performance of the lens barrel.\u003c\/p\u003e","brand":"Aerter","offers":[{"title":"Default Title","offer_id":48208819749089,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0821\/5193\/2129\/files\/5.png?v=1777889547","url":"https:\/\/aerter.com\/zh\/products\/%e9%ab%98%e6%80%a7%e6%80%a7%e8%83%bd%e5%85%89%e5%ad%a6%e7%b3%bb%e7%bb%9f%e7%b2%be%e5%af%86%e9%95%9c%e7%ad%92%e5%88%b6%e9%80%a0","provider":"Aerter","version":"1.0","type":"link"}
